Authors: Ostroukhov N. N. , Chumakova E. V.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The paper proposes a schematic diagram of an additional device for vortex propulsion units of vessels and algorithms for computer simulation of their use for various maneuvering options. The paper describes the advantages of vessels with propulsion units in the form of generators of vortex pairs, including toroidal vortices (thermals), the efficiency of propulsion units of which increases with the increase in their dimensions. A comprehensive analysis of the specifics of maneuvering of such vessels is presented. Practical inapplicability of traditional vessels’ devices for changing the course of the vessel and unacceptable duration of reaching steady-state modes and the stopping process when using only regular vortex generators are shown. A sequence of actions with vortex generators is described for the main types of maneuvers. In the paper, a schematic diagram of an additional device (with an estimation of its physical dimensions) is proposed to the vortex propulsion units of vessels, which ensures unwinding or braking of the «attached» mass for a predetermined time with minimal loss of power. Algorithms for computer simulation of the change in the nature of the flow in the closed flow region are developed using the proposed additional acceleration device. It is shown that the algorithms implemented in the work can be used in the control of a real vessel. Keywords: water transport, water vessels and aircraft with vortex propulsion units, surface and underwater (toroidal) vessels, flow in the vicinity of the vortex pair, drag, steady and transient modes, attached mass of water, blade, rotor.

RACK RAILWAY - A WAY TO THE TOP
Authors: Tikhonova T. Yu.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT Today there are more than 160 rack railways around the world. Constantly (in winter and summer) about 60 of them operate. Half of all permanent roads are in Switzerland, where, as is known, more than 61 % of the territory is occupied by mountains. A rack railway is a special type of railway with a steep incline, which has toothed wheel gearings, usually located between track rails. The author tells in some detail about the history of their creation, construction and operation. Currently, they are used as a means of moving along tourist routes in mountainous terrain or as urban passenger transport (for example, in Budapest, Zurich or Stuttgart). At the same time, the Swiss rack railways are profitable. In the territory of Russia, there are no rack railways. This despite the fact that in Russia there are also many mountain territories (≈ 33 %). And, as the author rightly points out, rack railways could promote their development and organization of activities that contribute to the development of the local community and the country as a whole. Keywords: mountain relief, tourism, rack railway, history, gear wheel, toothed wheel gearing, turn mechanism, spring shock absorber, Blenkinsop system, Abt system, Marsh system, Riggenbach system, Strub system, Morgan system, Loсher system, Lamell system.

RAIL CORRUGATION IN THE PROCESS OF BRAKING
Authors: Kargapoltsev S. K. , Novoseltsev P. V. , Kuptsov Y. V.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT It was found in the course of the study that oscillations of the vehicle wheelset’s angular velocity during braking should be recognized as the principal cause of rail corrugation. Over a single period, two alternating events occur: an elastic interaction between the wheel and the rail, and their slipping relative to each other causing friction and formation of a valley. The wavelength of corrugation wear increases with the increase of the train speed and the value of the braking torque. In order to reduce the intensity of wear, the track stiffness should be increased, the braking torque reduced, and the suspension’s parameters optimized. Keywords: railway, rail corrugation wear, wheelset, adhesion coefficient, braking torque, track longitudinal stiffness, angular velocity, wheel slip, friction.
OPTIMIZATION OF BRIDGE TRANSITION ZONES ON HIGH-SPEED RAILWAYS
Authors: Polyakov V. Yu.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The author studies issues of track service life and rail profile stability on bridges and bridge approaches, as well as safety issues on these sections at train speeds of up to 400 km/h. The optimal control theory of dynamic processes in the bridge-track-vehicle system makes it possible to synthesize structures that exert comparatively uniform impact on the sleepers (or other rail supports) in the bridge zone while maintaining the loads on the ballast closest to their design values. Optimal designs ensure a sufficient force of the wheel-rail contact thus substantially improving traffic safety. Keywords: railway bridge, train-bridge interaction, HSR, traffic safety, track stability.
A COMPARATIVE STUDY OF SERVICE QUALITY IN DELIVERING SELF-UNLOADING CONTAINERS
Authors: Ryabov I. M. , Gorina V. V.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT Containers offer cost-cutting opportunities in cargo transportation, loading/unloading operations, improving the efficiency of machinery and equipment utilization. This leads to continued growth in the volume of containerized cargo transportation; however, this growth is held back by the limited number of container terminals where containers are transferred to automotive transport that delivers them to the end receiver. To address this problem, the authors have developed a technology to deliver containers without the use of container terminals (cf.: World of Transport and Transportation, Vol. 14, 2016, Iss. 4). This article assesses the quality of transportation services provided by the old conventional technology in comparison with the suggested one that relies on the use of the self-unloading container. Keywords: automotive transport, transportable container, transportation technology, jack posts, container terminals, container yards, service quality assessment.

Authors: Denisov I. V. , Smirnov A. A.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].The background of the problem, objectives and methods are described in Part 1 of the article published in World of Transport and Transportation, Vol. 15, 2017, Iss. 4. ABSTRACT The vast majority of new automobiles are equipped with electromechanical power steering systems (EPS). These systems have clear advantages over hydraulic or pneumatic designs. At the same time, the service life of the EPS has not been fully studied. The EPS is a combination of electronic and mechanical subsystems, which puts certain limits on the application of existing diagnostic methods and tools typically used to monitor the performance and current health of a motor vehicle. This situation adds urgency to the development of standards for managing the health of motor vehicles based on diagnostic information, to organizing research results in this area into a system, and generally addressing the problem of improving the operational reliability of EPS systems. The results of the study should be helpful in developing a methodology for managing EPS reliability and fault-free operation. Keywords: automobile, steering system, electromechanical power steering, equipment health management, reliability, operation.

Authors: Filippova N. A. , Vasilevsky A. N.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The article considers options for car fleet outsourcing. The benefits of each method are evaluated, advantages and disadvantages are compared. A brief analysis of the state of the operational leasing market in Russia is given. When comparing financial and operative or operational leasing, emphasis is placed on their ability to optimize the costs of using and maintaining the fleet in terms of its own and external management. Reform of the leasing market in Russia is considered. The definitions of such concepts as outsourcing, fleet management, operative or operational leasing are presented. The functions of fleet management are analyzed and defined. Positive and negative aspects of operative or operational leasing are presented. Features of the advantages of operative or operational leasing are singled out. The direction of operational automobile leasing in Russia has just begun to develop actively - since 2004. The analysis of development of operative or operational leasing by years is carried out. The issue is considered in what the operational lease differs from the financial one. Specific examples are offered that prove that these are completely different types of services. This is due to the fact that the task of operational lease is to provide the client with a service, financial - to finance the client. With financial leasing, it is important that a leasing company acquires property for its transfer to a specific client - in contrast to an operative or operational lease, when the lessor independently chooses the equipment and the supplier based on the availability of demand for it. According to the RAEX (Expert RA) survey, in 2017 the volume of leasing business grew by 58 % and amounted to 710 billion rubles. The main drivers of the market due to the implementation of state programs are transport segments. At the same time, thanks to deals with railway and aircraft engineering, the share of operational leasing in the new business reached 21 %. The main contribution to the development and growth of the leasing market in Russia in 2018 will be made by the automotive segment, the development of additional service programs and the client-centered approach of leasing companies. Keywords: car fleet outsourcing, fleet management, operational leasing, financial leasing, leasing market growth, leasing market reform.

MOSCOW CIRCULAR RAILWAY HAS A LONG TRACK RECORD
Authors: Stolbova I. D.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The Moscow railway junction, rapidly developing, by the end of 19th century no longer coped with cargo transportation. The reason for this was the dead-end organization of the stations, both in Russia and Europe, which played the role of terminal stations in large cities. After many but unsuccessful attempts to unload the railway terminal in Moscow, a decision was made to create a circular railway (Moscow Circular Railway (MCR)) in order to connect the dead-end radial branches and make the system more flexible and maneuverable. Well-known architects and engineers were invited to design and build the new railway, budgetary funds were allocated, emphasizing the special importance of the facility for the state: the European countries and Russia stood on the verge of the First World War, and the predictable collapse of rolling stock threatened the railways with inevitable calamities. Under these conditions, MCR became a universal complex of engineering structures and civil buildings, not only serving transshipment of goods and transporting passengers, but also containing pedestrian overpass bridges and soldiers’ barracks for mobile transfer of troops, as well as telegraph and telephone points of communication. This railway has been operating for 110 years and after reconstruction has received a new appointment as part of urban passenger transport. Keywords: Moscow Circular Railway, history projects, architecture, stations, bridges, stations, topography, reconstruction, urban transport functions.

MODEM OPTIONS FOR DIGITAL RADIO COMMUNICATION SYSTEMS
Authors: Volkov A. A. , Kuzyukov V. A. , Morozov M. S.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT New versions of the modulator and demodulator (modem) for the digital railway radio communication system GSM-R have been developed, which increase the noise immunity twofold. To realize «cos» and «sin» blocks, a phase modulator is used, two coherent quadrature demodulators are connected to its output in parallel. It is shown that «cos» block generates the signal cos [msinφ(t)], which is transferred to the operating frequency of the transmitter by means of subsequent blocks representing the structure of the one-side amplitude modulation driver, forming the final phase-modulated signal. It is proposed to detect an FM signal not from the modulation envelope, as it is done customary, but coherently, which excludes the quadrature component of the interference. Keywords: railway, radio communication, digital signal, Gaussian filter, modulation, coherent FM signal detector, noise immunity, frequency efficiency.

A more rational technology is proposed with the use of a container developed by the authors with folding load-lifting pillars, which makes it possible to reduce the number of stages by almost half. The analysis of the factors determining the efficiency of road transport in the maintenance of containers based on the proposed self-unloading models is carried out. Keywords: car, mixed transportation, transportable container, load-lifting pillars, terminal complexes, cargo delivery, quality of service.
INTRODUCTION OF NANOTECHNOLOGIES AT RAILWAY FACILITIES
Authors: Nedorchuk B. L. , Pashinin V. A.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The paper considers one of the promising directions for obtaining nanopowders by grinding materials in mills of various types and high power, as well as by dispersing alloys with a liquid or gas stream. Such nanopowders can be used as additives in the foundry industry in order to obtain more substantial strength characteristics of products intended for railway equipment. Widespread introduction of nanotechnology will ensure the dynamic development of Russian transport engineering and the creation of economical, highly efficient equipment that meets the requirements of reliability and sustainable operation of the transport complex.

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT In the system of railway traffic organization, the forecast of passenger flows is an information and analytical basis for development of train schedule and calculation of train schemes. For making sound management decisions, high accuracy of the forecast and a methodological base that meets modern conditions are necessary. The article is devoted to the study of the methods of calculation of passenger traffic, taking into account the specifics of their formation in the federal entities of the Russian Federation. A classification of regions according to the characteristics and trends in development of demand is proposed. The choice of an approach to forecasting the volumes of intraregional demand was carried out on the basis of the algorithm developed by the authors. The results of calculations are presented and the areas of application of forecast methods are determined depending on the local features identified. Keywords: railway, regional passenger flow, traffic forecast, local transport market, demand trends.

Authors: Levin D. Yu.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT From automatic tracking of fulfillment of one of many variants of a plan for train formation, it is time to move on to a flexible operational system of its timely adjustment. The management of car flows should include two systems: long-term and operational. The long-term goal is to solve in advance issues related to direction and distribution of car flows, correspondence between the number of train assignments and loading of technical stations with possibilities of track development and processing ability. The operational system should react to changes in calculation standards and values of car flows, increase or decrease the technical capacity of structures, infrastructure devices and rolling stock, difficulties in operating work. The inclusion of dispatchers in organization of car flows will allow to optimize implementation of the plan for formation of trains. Keywords: railway, organization of car flows, plan for formation of trains, dispatching management.

Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The article is devoted to development of a universal terminological apparatus for a clear grouping of various terminal-warehouse infrastructure (TWI) objects by their functional types and position peculiarities in the cargo delivery system. On the basis of the analysis of the scientific literature, a lot of definitions of the concept of «TWI object» are visualized. An analog logistic functional is considered and classified. The interpretation of the term «logistic object» is offered, a comparative analysis of existing and proposed definitions is made. The new terminology will allow to consolidate a comprehensive, unified approach to the study of TWI objects, which can later become an applied tool for compiling parametric series and forming standardized requirements for such objects.

Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT In dealing with issues related to investigation and examination of road accidents, preference is usually given to measurements and quant i tat ive assessments, while qualitative analysis and assessment are allowed. When carrying out expert studies, the source of the initial data is the results of an inspection of the place of the road accident, inspection of vehicles, photographs, diagrams showing traces and other objects bearing information about the event. The actions of experts should help to increase the volume of information (re-examination, experimental modeling of tracks, request for additional data). The article deals with theoretical aspects of expert heuristics, including purposes and possibilities of examination, the types of process models and their constituent elements. Examples of heuristic conclusions are presented in the analysis of damage to vehicles resulting from of road accidents. Keywords: road, road accident, expertise, heuristics, damage to vehicles.
