An action-oriented approach to didactic dubbing in foreign language education: Students as producers
Authors: Escribano Alejandro Bolaños-García , Navarrete Marga
Published: May 2022

This article discusses the action-oriented foundations of TRADILEX (Audiovisual Translation as a Didactic Resource in Foreign Language Education), a project funded by the Spanish Ministry of Science and Innovation, which involves researchers from twelve universities across Europe and the UK. This project focuses on the improvement in the linguistic skills perceived through audiovisual translation (AVT) practices such as the use of captioning (i.e., interlingual and intralingual subtitling) and revoicing (i.e., dubbing, voice-over, and audio description) through an action-oriented approach (AoA). The ultimate objective is the study of AVT as a means to enhance learners’ communicative competence and reception, production, and mediation skills in an integrated manner. Following the design of a methodological proposal for a didactic sequence of AVT tasks, proposals are currently being piloted with B1 and B2 adult learners of English as a foreign language utilising – and adapting – the recent illustrative descriptors (Council of Europe, 2018) for AVT instruction. The potential benefits of action-oriented AVT tasks in foreign language education (FLE), in which foreign-language learners become active producers of AVT work, are put to the test employing empirical inquiry and thereafter advocating for more comprehensive integration of AVT in the FLE curriculum overall.

In the context of the rapid development of technologies and various methods of communication, as well as the growing role of information in the life of society, information genres in different types of media are of particular importance. Currently, they are experiencing a stage of serious competition with new technological possibilities of forms for obtaining and creating information. The basis of progress in human society is recognized as a well-founded entity such as verbal communication. Human society today is most interested in the information that the media presents to it. The modern world is characterized by the active use of various information technologies, as they save time. Television messages are responsible for obtaining the necessary information in a short time. In other words, a person tends to emphasize information mainly from the Internet, television messages, from newspaper information. Television news releases often contain news blocks in English that need to be translated. Today, it is an urgent need, and it is valid and necessary in a variety of ways. This and many other factors explain the urgency of this problem. One of the main goals of knowing the world is the need for information. It is due to the subconscious desire of people to understand what is happening around – the desire in which the instinct of self-preservation and the orienting reflex that guides human development manifest themselves. At the moment, the media have such a significant impact on the life of society, on the consciousness and ideas of people. Modern mass media have a substantial effect on the life of society, on the consciousness and ideas of people. Society constantly needs to receive new information about what is happening globally.

Published: May 2022

Objective: The aim of this study was to investigate whether these applications are effective in quitting smoking by using one of the smartphone applications in addition to motivational interviewing in patients who applied for giving up smoking.

Materials and methods: A randomized controlled intervention study was between January and July 2020. Adults aged 18-65 years who smoke at least one cigarette a day were included in the study. In the prospective study, the patients were followed for 6 months and a total of ten interviews were made. A phone application was installed on the intervention group. Afterwards, the smoking status of the patients was evaluated by telephone or face-to-face.

Results: Sixty-three smokers participated in the study. Fifty patients completed the study, 25 controls and 25 interventions. Long-term smoking cessation findings at the first, third and sixth months were evaluated for both groups. Success rate in the first month was 64% for intervention group and 32% in the control group; for the third month it was 56% in the intervention group and 32% in the control group for the sixth month it was 44% in the intervention group and 24% in the control group.

Conclusion: The smartphone mobile-application showed a positive effect in promoting the increase in the smoking quitting rate. The intervention was found to be effective in 30-day smoking cessation success. Despite higher smoking quitting rates at 3 and 6 months, the application was not effective.
Loyalty Conflict and Parental Alienation in Children with Divorced Parents
Authors: Iacobescu Maria-Rodica
Published: May 2022

A divorce can have painful consequences, especially for the children, as they can develop loyalty conflicts or parental alienation. The custody problem increases the rate of disagreements between parents and the smallest decisions can become opportunities for physical, moral or judiciary confrontation. Conflicts can be accompanied by the formation of an alliance between one parent and the children, in order to disqualify and denigrate the other parent. According to R. A. Gardner, extreme conflicts can lead to the development of a so-called Parental alienation syndrome, the painful cases in which the children, after a divorce, refuse to see a parent due to a combination of indoctrination fueled by the alienating parent and the child’s own contributions towards the denigration of the targeted parent. This syndrome still is a topic of debate for researchers, some of them agreeing with its existence while others argue that it lacks scientific value.
Transforming Parks into “Magical” Places for Play: Evaluating the “Meet Me at the Park” Play Spaces Grant Program
Authors: Slater Sandy J , Pugach Oksana , Ragonese-Barnes Marina , Banner Rachel
Published: May 2022

In 2017 the National Recreation and Park Association launched an initiative entitled “Meet Me at the Park: Transforming Parks and Improving Access to Play Spaces.” The purpose of this grant opportunity was to fund innovative and scalable projects that transform parks and improve access to play spaces for kids of all abilities (aged 3-11) and their families in underserved communities. To date, there have been three funding cycles. Each cycle funded a total of 25 park projects (Sample N=75) that were tasked with providing access to renovated play spaces to increase physical activity in the most underserved communities using innovative and scalable solutions. A sample of 24 parks (8 per cycle) were selected for an in-depth evaluation using a pre-post study design. Two primary data collection activities were conducted: 1) collecting systematic observations of play and recreation in communities (SOPARC) pre- and post-renovation of play spaces; and 2) collecting intercept surveys from 32 adults pre- and post-renovation of play spaces. SOPARC results showed significant increases in daily park use (20 vs. 37 visitors on average per day at baseline compared to post-renovation), and a 31.5% increase (p<0.001) in the number of people engaged in moderate to vigorous physical activity (MVPA). Intercept survey results showed a 17.54 percentage point increase in the number of survey participants visiting the park for the first time. There was a 26.73 percentage point increase in the number of respondents stating that the park gave the kids a chance to experience something new and a 19.32 percentage point increase in respondents stating that the child they were with played more since using the park post-renovation. Results of the evaluation show that the investments in play space renovations were positively associated with increased park use, MVPA, and children’s park-based play. This information is important for park and recreation agencies, park and recreation advocates and elected officials to show that high quality, well-maintained parks are essential to improve public health outcomes and use of park spaces.
Politics, Parks, and Pandemic: A Research Note
Authors: Scruggs Caleb J. , Zajchowski Chris A. B. , Huggins Jennifer , Burns Alexander
Published: May 2022

The COVID-19 pandemic highlights the importance of parks as critical infrastructure for societal well-being; however, for much of the pandemic, the risk for disease exposure and transmission in these spaces was unclear. Public health messaging by parks continues to attempt to influence health-promoting behaviors, but the impact of advisories may vary due to the message source. In fall 2020, we surveyed park visitors in Virginia, U.S. across political affiliations to understand decision-making factors influencing visitation. Results indicate many similarities in decision-making factors across political affiliations, such as the perceived importance of health benefits derived from outdoor recreation. Significant differences in the perceived importance between message sources (i.e., Trump Administration) (ηp 2 = .104) and risk perceptions related to COVID-19 (ηp 2 = .228) across political affiliations were evident. These findings demonstrate the importance of attending to political affiliations when crafting messaging strategies, not limited to the context of the COVID-19 pandemic.

Authors: Gorączko Marcin , Pawłowski Bogusław
Published: May 2022

The article synthesises the results from observations of ice phenomena on Warta River in Uniejów in years 1947−2012. From beginning of 1980s average time, in yearly perspective, in which the river was frozen was over two months, with ice cover appearing almost annualy. The years in which the river was frozen the longest are were 1947, 1954−1955, 1962−1964 and 1979, which coincides with the occurrences of coldest and longest winters in this region of Poland. The research shows however, that the ice phenomena on Warta River in vicinity of Uniejów, are determined not only by climate factors, but also, in a great extent, by Jeziorsko Reservoir, from the very beginning of its utilization. Construction of this reservoir, completed in 1986, resulted in a decrease of the duration of ice occurrences by nearly three times, and the complete freezing of the river became a rare phenomenon.

Authors: Paterski Karol
Published: May 2022

The article describes stages in the formation of voluntary fire brigades on the territory of former communes of Skotniki and Kościelnica in 1918. Examples of localities where such fire brigades were organized are Czepów, Wilamów, Orzeszków, Ostrowsko and Wielenin. The managing body of the joint Czepów-Wilamów unit was almost entirely composed of Czepów residents. When this fire brigade was divided into two units, the firemen from Wilamów joined the National Fire-Fighting System. As the centenary of the existence of these fire brigades is approaching, it is worthwhile to remind their organizational beginnings, which took place at the time of re-creating Polish statehood after a long period of partitions.

Published: May 2022

This study aims to determine the impact of the geographical conditions of an area on the phenomenon of sirri marriage through a qualitative study. Data analysis was carried out inductively from the results of observations, in-depth interviews and FGDs. The results of the study indicate that the phenomenon of unregistered marriage occurs in Sumber Malang, Situbondo, East Java as a result of the geographical conditions of the area. The topographical conditions of the area in the form of mountainous areas with an altitude of 500-1,250 meters above sea level, very steep with a slope of 45%, rocky and dry soils make the Sumber Malang area difficult to develop economically. This is because agricultural cultivation is difficult to develop. Furthermore, the accessibility of areas that are difficult to reach because they are far inland, narrow roads, no public transportation, far from the center of economic activity have caused people in this area to choose to stay in their environment. Topography and regional accessibility have an impact on adolescent marriage behavior in the Sumber Malang community. Adolescents and parents view unregistered marriage as something that is done to avoid sin, the certainty of a relationship, economic motives (because the cost of marriage is considered expensive by the community) and as a result of the remote location of the area; because the teenager only has a circle of friends in Sumbermalang. There are two patterns of sirri marriage that occur, namely teenagers will marry sirri and live together and teenagers will marry sirri then stay with their parents and still continue their education. The implication of this research is to provide an illustration that geographical space can affect the pattern of marriage that occurs in society. Based on this, the relevant government can provide adequate access to education at the research sites.

Emergency states that arise at influence of free fire on an oil and gasoline tank shell lead to thermal stress that can cause shell damage, a decrease of hardness and material strength. The paper considers a method for determination of a non-steady thermal field of the shell in a fire centre. Besides, the authors have got a thermal conductivity equation in partial derivatives and suggest a new approximation of the thermal field in the form of polynomials. The method is realized in the MathCad program complex and can be used at design of railway tanks for transportation of dangerous freights and at development of systems for protection from emergency thermal influences.
Automatic urban transport
Authors:   Brest State Technical University (BrSTU), Shut’ Vasiliy Nikolaevich
Published: May 2022

Development of information technologies allows revising a concept of organization of modern urban transport and its control. Meanwhile, it is possible to eliminate and to reduce all urban passenger vehicles to a single transportation unit with nominal capacity called an infobus. The infobus is an unmanned electric car with small capacity (up to 30 passengers). On its basis the author has developed a design of an intelligent transportation system for mass transportation of passengers. This type of public transport is fully automatic and is designed for the increase of quality and flexibility of passenger traffic organization. Besides, it differs by significant economic benefits because its performance is approaching the performance of metro, but at the same time the infobus is characterized by lower cost of production and maintenance.

Strength of a railway track is determined by strength and a distributing ability of bearing elements (rails, plates, sleepers, ballast and subgrade). All things being equal, the higher the strength of the material for bearing elements of a railway track or the better the distributing ability of elements (rails, sleepers, plates, ballast), the higher the strength of a railway track. The paper presents a new method for calculation of the required strength of a railway track with the consideration for the intensity of its use. The required distributing ability of rails is determined based on the fulfilment of strength conditions for sleepers, ballast and subgrade. According to rules of the strength calculation of a railway track, values of influence of rolling stock wheels are calculated in one (calculated) cross section of a railway track. Meanwhile, statistical properties that are characterized by a variation coefficient are determined by various influences on a track in the calculated cross section of different wheels of rolling stock. With the use of a system of equations it is possible to calculate the required strength of the railway track with the consideration for the intensity of its use.

Published: May 2022

Laying of geosynthetic materials is one of the efficient methods for stabilization of railway track sleeper bearing. Side keeping is the main mechanism of stabilization that allows improving characteristics of sleeper bearing and as a consequence allows increasing bearing strength. The paper considers an approach to modeling of geogrid both in unlimited and limited ground conditions. A numerical model is firstly checked by test results and then is used for studying behaviour of the geogrid in ground body. For the modeling of the geogrid behaviour at tensile loading the authors carry out a nonlinear analysis by the finite element method. At tensile loading the model covers bands of elastic and plastic areas of the «stress-strain» dependence. The geometry of the geogrid is modeled with its detailed characteristics including flange thickness.

On the relationship of natural oscillation frequencies and critical loads in assessing the rigidity of load-bearing elements of carriage structures
Authors:   Russian University of Transport (MIIT), Grigor’ev P. S.
Published: May 2022

The regulatory and technical documentation clearly defines the requirements for assessing the bearing capacity of rolling stock units, for example, to check the design being developed for loss of stability under the influence of compressive loads. This involves performing verification by calculation methods. The article considers the possibility of determining the critical level of external overpressure on the shell of the tank cauldron on the basis of experimental data on the minimum frequency and shape of natural oscillations. In order to solve this problem, the differential equation of flat cylindrical shells is used. The equation used was proposed by Donnell and has proven itself well in calculation of cylindrical shells, in particular cauldrons of tank cars. The peculiarity of the proposed solution lies in a certain analogy of the mathematical description of the processes of loss of stability and natural oscillations. As a result of transformations of the differential equations under consideration, an expression is obtained that connects the critical level of external overpressure and the natural oscillation frequencies of the objects under consideration. Numerical values of the studied parameters are given, the reliability of which is confirmed by similarity with the data given in previously published sources. Recommendations are given on application of the proposed approach in engineering verification of carriage structure elements stability. The necessity of taking into account the forms of oscillations and loss of stability when determining the level of critical pressure by the obtained expression is shown.

Published: May 2022

When studying wear, it is necessary to know the classification of its types and subtypes, but this is complicated by the fact that there are no uniform signs by which wear is classified. The components of the mechanical part of the traction rolling stock are particularly susceptible to wear. The authors propose a new specialized classification of wear types which act specifically on the mechanical part of the traction drive of locomotives. Various classifications of wear types are presented. Based on the existing classifications, the authors have developed a specialized adaptive scheme of wear types affecting the mechanical part of the traction drive of locomotives. In this classification, the molecular-mechanical type and other subtypes of wear are clarified and revised. The classification of wear types is based on physical, mechanical and chemical phenomena in the contact zone. The article substantiates the lack of existing subtypes of wear in the developed classification due to the minimum possible probability of manifestation on the elements of the mechanical part of the traction drive of locomotives. Examples of negative impact are given. A model of subtypes of mechanical wear is proposed, describing its intensity as a regularity of the change rate in wear during the operation of the part. It is indicated that mechanical wear is the predominant type. The main quantitative characteristics of the wear process are described.

Published: May 2022

Some results of the study of weighted codes with summation of different values of weight coefficients in the ring of deductions by an arbitrary modulus are presented. Such codes have not been studied in detail in the research literature. The rules for constructing weighted codes with summation are given. The peculiarities of the choice of module values and weighting coefficients for building a code with the detection of any single errors in code words are explained. The article focuses on experimental studies of the use of summation codes to detect errors at the outputs of control combinational circuits. During the experiment with control combinational schemes, the patterns inherent in this class of codes are established and described. The patterns are associated with specific ratios between the weighting coefficients, which give the same detection characteristics of the integrated control scheme. It is shown that, despite a great variety of ways of weighing the digits, some of the resulting weighted codes with summation have the same characteristics of error detection at the outputs of combinational circuits. The results of the study should be taken into account when building digital devices and systems with fault detection, when improving the means of automated design and synthesis of modern and developed microelectronic control systems.

Published: May 2022

The idle time of shunting locomotives in standby mode is up to 50% of the working shift time. When the locomotive is idling in the cold season, it is necessary to maintain the diesel engine in the «hot» state, i.e. the diesel engine is idling, at different positions of the driver’s controller. The article presents research of the effect of the diesel locomotive in idle mode on the wear of the limiting parts of the diesel engine, namely, on the cylinder bushings of the locomotive. The method of calculating the amount of wear of parts depending on the operating time of the diesel engine at each position of the driver’s controller is given. The presented mathematical model is developed using machine learning models, standard deviation tools and a simple iterative method. The results of the research prove that up to 10% of the wear of the diesel engine is accounted for the self-heating mode when the locomotive is idling. The presented results once again substantiate the need to use alternative methods of diesel self-heating, when external heat sources are used to keep the locomotive in a «hot» state.
Comparison of the energy efficiency of ac electric freight locomotives with collector and asynchronous traction drive
Authors:   branch of Samara State Transport University in Nizhny Novgorod, Marinin S. A.
Published: May 2022

Electric locomotives with asynchronous traction drive are operated on the Russian road network in passenger and freight traffic. The advantage of such a drive is a large specific power. At first glance, electricity consumption of an electric locomotive with asynchronous traction drive should be less than that of an electric locomotive with a collector traction drive. The same is declared by manufacturers of traction rolling stock [1, 2]. But the answer to the question which electric locomotive is more economical in freight traffic: with a collector or asynchronous traction drive? - is far from being unambiguous [3, 4, 5]. In order to determine which electric locomotives have the best energy efficiency regarding the traction drive, a comparison of electric energy costs for traction of freight trains by electric locomotives of the VL80S series with collector traction drive, operated in two- and three-section versions, and a promising two-section electric locomotive of the 2ES7 series with asynchronous traction drive was performed. The energy efficiency assessment was carried out using methods based on elements of mathematical statistics and probability theory, including estimation of the distribution parameters of the studied quantities, statistical hypothesis testing and variance analysis. This article presents the main results of the research carried out at the testing area of the Gorky Railway during the pilot operation of the 2ES7 series electric locomotive on the Druzhinino - Vekovka section.
Assessment of the influence of train weight and driving mode on the interaction forces in the «wheel-rail» contact zone
Authors:   Ural state university of railway transport (USURT), Parakhnenko I. L.
Published: May 2022

The article presents a study to assess the impact of the introduction of heavy-weight traffic on the main forces of interaction arising in the «wheel-rail» contact zone while a freight train is in motion along curved sections of the railway track. Mixed traffic is used on domestic railways, but there are no dedicated specialized lines for the operation of high-speed passenger and freight traffic with increased axle load. In this case, the possibility of the track infrastructure becomes decisive. Improving the operational efficiency, first of all, of track facilities, is impossible without scientifically based methods. The qualitative operation of a track depends on the forces arising from the interaction of the wheel-rail pair. This paper presents a study of the force interaction of the contact zone with an increase in the axle load on one of the sections of the Sverdlovsk railway. Horizontal transverse lateral and longitudinal forces are considered by means of simulation modeling. Since the introduction of heavy-weight traffic is caused by the change in the traction characteristics of a train, the article presents the results of work on the study of influence of the train driving mode on the forces under consideration.
Improvement of the system of auto-regulation of braking modes of an electric train with a pulse converter
Authors:   Ural state university of railway transport (USURT), Sulejmanov R. Ya.
Published: May 2022

The article discusses the features of automatic regulation of the process of electric braking of a DC electric train. The peculiarity of this process is that traction engines switch to generator mode of operation to reduce the travelling speed. Industrial generators operate at a constant rotational speed and constant voltage. On an electric rolling stock in braking mode, electric machines operate at a continuously changing rotational speed. At the same time, the objective is to maintain a constant level of the set value of the braking force to ensure comfortable conditions for passengers. At the theoretical level, to accomplish this task, it is sufficient to keep the specified braking current constant at a changing rotational speed, which can be done by regulating the excitation current. In real conditions, the traction engine passes through four high-speed control zones, each of them is characterized by its own control algorithm. As braking progresses, it is possible to distinguish - a zone of high speeds, a zone below the running speed, where the process of pulse regulation of the armature current occurs (by pulse shorting of the circuit) and a zone of short-circuit of the armature circuit. The running speed is the speed at which the armature voltage is equal to the mains voltage at the rated excitation current. Within a high-speed zone, the excitation current is regulated, below this speed, the excitation current is maintained at a constant (nominal) value. The regulation of the excitation current is carried out by the control unit of the armature and excitation currents. Transitions from one zone to another are made using nonlinear elements. If the ratio of the armature current increment to the excitation current increment is considered as a transfer function, then in the high-speed zone this function is not constant. If a control system is adjusted in relation to the highest speed of movement, then in the zone of reduced speeds, performance of the system in response to voltage changes in the contact network will be insufficient. When the speed decreases, the magnitude of the transfer function decreases, and this dependence leads either to undesirable self-oscillations, or to a slowdown in the control process. In order to eliminate self-oscillations and improve the quality of regulation, it is proposed to provide in the control unit the possibility of changing the gain of the armature current regulator depending on the speed of movement and the operating mode of the traction electric drive.

The article discusses the problems of uneven arrival of vehicles at the transport and logistics center (TLC) and identifies operational problems that arise at the time of cargo transshipment between different modes of transport. The effects of the irrational use of loading and unloading machines and ways to reduce the identified negative impact are determined. The main approaches to modeling the moments of arrival of vehicles in the preparation of technological documents for the operation of the logistics complex (contact schedule of the complex, the schedule of trains on the adjacent section) and the daily schedule of the work of the junction station are highlighted. The uniform supply of vehicles, characteristic of dispatching the supply of modes of transport, is relevant for modeling the operation of the supply of groups of wagons to the terminal. In case of uneven arrival of vehicles, areas of concentrated and sparse supply of vehicles are allocated. For these periods, the reasons for downtime and irrational increase in operating costs for processing one ton or intermodal unit of cargo are determined. In order to determine the nature of intra-day irregularity of the supply of vehicles, a method has been developed based on identifying the functional dependence of the arrival of vehicles during the day and constructing an appropriate histogram of the distribution of the arrival of vehicles corresponding to the selected time intervals during the day, which allows us to get a general idea of the nature of the arrival of modes of transport of various parameters. Modeling the operation of the terminal and logistics complex in the market economy with unpredictable moments of arrival of vehicles and uneven arrival of transport, special attention should be paid to the mode of operation of loading and unloading machines and crews at different times of the day when developing the technology. The allocation of periods of condensed and sparse supply of transport enables us to adjust the operation of the terminal to optimize operating costs and reduce the total cost of cargo processing, and the attraction of additional processing capacities during peak periods will minimize downtime of vehicles waiting for processing.

The article discusses the application of the life cycle contract (LCC) for the transport industry in Russia. The purpose of the study is to detect the problems of LCC and identify prospects for expanding the topics of LCC management for the purchase of different types of vehicles. The definition of LCC according to 44-FZ is given, the essence of the form of interaction between the customer and the contractor is revealed. The main documents regulating the objects of procurement for LCC are listed, changes and amendments to these documents are proposed. The types of vehicles that can be purchased by LCC are indicated. The advantages of using LCC for the purchase of vehicles are described. Information about the scientific base in the field of LCC is mentioned and an assessment of the practical application of long-term contracts in Russia is given. An example of an existing LCC for the supply of electric buses in Moscow is analyzed in detail. As in the example, the main provisions and the sequence of concluding a contract with a state customer are considered. The data for the last four years on the conclusion of the LCC between the State Unitary Enterprise «Mosgortrans» and vehicle manufacturers are presented. The stages of the life cycle that are not included in the existing LCC are identified, the reasons for their lack are substantiated. It is proposed to introduce a new form of contractual relationship between the customer and the contractor in B2B and B2C segments to transfer the principles of LCC to other markets with the introduction of a new concept for these markets. The evaluation of the state of the age structure of the urban transport park, air and water vessels is given. The main problems of LCC implementation are considered. The prospects for expanding the topics of LCC management are determined. The authors raised the issue of vehicle recycling and the lack of recycling facilities proposed and justified recommendations for the creation of recycling enterprises for urban transport. Organizational and technological issues regarding the construction of a recycling system are touched upon. The main provisions for solving the LCC problems and the release of long-term contracts to a new level are formulated.

The article is dedicated to the memory of professors T. G. Yakovleva and V. V. Vinogradov, who made a great contribution to the development of the design issues, calculations and modelling of reinforced soil structures. Based on their research, the methods of designing and calculating of reinforced soil structures for strengthening the roadbed of railways were developed and successfully applied for the first time in the USSR and Russia. The continuation of this process was the introduction of the materials into educational process of the RUT (MIIT) in the “Railway track”, “Roadbed in difficult conditions” and “Software for calculating railway track structures” academic disciplines. Laboratory research on designing and calculating of strengthening of roadbed using reinforced soil structures has been elaborated. Further development was the study of the interaction of modern geosynthetic materials with the ground in reinforced soil structures.

The article discusses the study of the impact of track irregularities on the intensity of rail wear. The relevance of this issue derives from the necessity to develop approaches to reduce the intensity of lateral wear in curves. The objective of this research paper is to estimate the parameters and magnitude of deviations of the track in plan which affect the intensity of rail wear. In order to resolve this issue, modelling methods implemented in the “Universal Mechanism” software environment (UMLoco module) have been used in this paper. The initial data has been obtained as a result of the tachometric transit survey conducted on the Samara – Chelyabinsk route in 2019-2020. The results of this paper include an analysis of the calculated indicators of interaction of the track and rolling stock, particularly, lateral forces and the intensity of rail wear.

At present, the indicators of durability of railcars and their components and parts are defined by the concepts of “lifetime in service” and “assigned lifetime in service”. These concepts do not fully reflect their operation processes and prevent from predicting, managing and regulating economically the technical parameters and properties of the railway rolling stock. A more thorough and all-encompassing parameter which determines the operating lifetime of an object is its life cycle. This research paper deals with the issues related to the determination of life cycle of the springs of an axle box suspension bogie of the ES2G electric train “The Lastochka” (“Swallow”).
