Authors: Leontev M , Magera T 
Published: October 2020

Abstract
Digital technologies, globally introduced in the urban environment and made available to the majority of the population only in recent years, are relatively new phenomenon. This paper discusses the circumstances of the transition of the transport industry to the “digit” as an example of studying the theme of human factor in the digital world. The main professional groups united around the unified digital platform for the transport industry were taken into account, the possible changes due to the transfer to the unified digital platform for the transport industry were studied, and the current state of the transition of the transport industry to Industry 4.0 was assessed. In the process of implementing digital technology, problems are found in the boundary layer of the interaction of the human factor with technical and digital factors, it should be noted that these factors are mutually complementary. Therefore, when transferring the transport complex to the unified digital platform, emphasis should be placed on effective training and retraining of personnel not only in connection with digital technology, but also in programs of emotional competence and intergroup adaptation for managers and employees.
Selection of the number of digits of histograms for random characteristics of the dynamics of the transport system
Authors: Manshin Y P , Manshina E Yu 
Published: October 2020

Abstract
The article deals with the experimental studies of the machines, characterized by many random dynamic effects, both from the working bodies, and from the microrelief of the fields where the technological process is carried out, and the roads when the car is moving. The histogram of a dynamic random process, as the main means of systematization, requires optimal selection of the number of discharges to obtain the effects of factors distribution patterns. The selection of the number of discharges for the histogram distributions of experimental data sets is the key to the theoretical compile statistics. The method is illustrated using a histogram comparing a stepped histogram of an empirical distribution and a theoretical law similar to a normal one. The methods of selecting a rational choice for the number of digits is presented, that allows with the required confidence probability, to obtain correspondence of empirical histograms to the theoretical laws of distribution of random variables, for which it is proposed to use the criteria of agreement of Student, Fisher, Cochren and others. Formulas are proposed for determining the number of digits in cases of similarity of the histograms to the theoretical laws of distribution of random Gauss (normal), Rayleigh, exponential, gamma distribution, log-normal, beta distribution and other laws. Numerical testing of the method for the dynamic support reactions of the car during its movement along the microrelief is given.

Abstract
Leaching corrosion by dissolving cement stone from ordinary Portland cement (cement stone from general construction (GCC)) and cement for transport construction in water and chloride solution was investigated. Stone from GCC in water dissolves on average 3 times faster than transport cement and in chloride solution under similar conditions – 2-4 times. The addition of silica fume to cement reduces the solubility of transport cement stone by 3-5 times, and impregnation with compounds that reduce the solubility of lime by 2-4 times.

Published: October 2020

Abstract
Destruction of reinforced concrete supports is a complex physical and chemical temporary process. The inevitability of destruction is due to the nature of the materials used and the activity of the environment. Centrifuged concrete is an extremely heterogeneous material over the thickness of the products made thereof: in centrifuged structures, several layers are formed over the wall thickness, which differ in their texture and structure. While in operation, the supports are subjected to a complex temperature impact, microorganisms and chemically active media have an impact on them. In addition to the main adverse factors, it is worth noting the effect of the electromagnetic field of the catenary suspension, the impact of which promotes the formation of transverse cracks mainly in the upper part of the support. Therefore, this phenomenon requires the study and development of reinforced concrete support diagnostics and monitoring facilities to provide continuous movement of railway transport and prevent support breakage and falling.

Published: October 2020

Abstract
The interior design of hotel inevitably includes the furniture installation. The design of furniture needs to select suitable material. Modern material production provides numerous alternatives but at the same time create another problem of selection the suitable one. The properties of materials in different aspects, e.g. strength, style, durability, etc., form a set of criteria in the selection. The criteria are normally conflicting and pose difficulty in the selection process. This paper proposes an MCDM methodology, namely interval TOPSIS, to facilitate the selection process by ranking the prospect materials according to a set of criteria. The interval TOPSIS is suitable for the real-world application where there is uncertainty in terms of interval numbers. The methodology is illustrated through an illustrative example. The methodology is readily extended to the material selection in other domain of application.

Published: October 2020

Abstract
The article describes the application of rolled floor materials for sound insulation of impact noise by the floors. A detailed classification of such materials is given, including such materials as linoleum, rubber linoleum and carpet. The described method is appropriate for testing the floor to obtain the frequency characteristics of the normalized level of impact noise of the whole structure and for the frequency characteristics of improvement of sound insulation due to the use of roll coverings. Methods for normalized impact noise level indices calculation in case of composite construction and only roll covering are also briefly described. A new semi-graphical method for constructing the frequency response of reducing the level of impact noise by floor covering for inserted floors is presented. A computational model for solving the contact problem of the impact noise isolation by floor in the form of an oscillatory system, consisting of an absolutely solid body and a two-layer elastic medium, is presented. The solution of the contact problem for obtaining an adjustment for reducing the normalized level of impact noise due to the application of a roll material is shown. The equation for frequency of crumpling for the linoleum surface crumpling in the process of standard striking machine’s impact is shown. The effect of local crumpling occurs and the growth of sound insulation starts in two-layer floor from this frequency’s value. The analysis of calculations accordingly the proposed calculation method is carried out. The practical algorithm for semi-graphical method and for the frequency response plotting of impact noise sound insulation improving by the roll floor covering is proposed. Graphs of the magnitude of impact noise improvement by the most common roll materials, that can be used to obtain the frequency response of impact noise isolation by a two-layer floor, are given.

Abstract
The article presents a General principle for evaluating the norms of specific energy consumption rates for ore extraction at mining enterprises, including the determination of daily well penetration and conversion coefficients of specific consumption for individual operations. Specific norms of electric power consumption for excavating and drilling are determined according to the developed methods. Analyzing the nature of the waveforms, it can be concluded that the greatest energy consumption during excavation is accounted for by the scooping process. When comparing individual cycles on oscillograms, it is seen that at almost the same maximum power, equal to 0.465 MW, a significant difference in the energy consumed per cycle (from 4.9 to 8.2 MW·s) occurs due to different scooping times. The economic feasibility of improving the crushing of rock mass by explosion to reduce the specific cost of electricity was determined, which allowed us to conclude that it is not advisable to make additional investments in drilling and blasting operations in order to reduce electricity consumption. As for drilling machines, the average electrical power consumed by one machine is determined based on the results of measurements. The power consumption was recorded taking into account the shunting operations of the machine. By integrating the load curve using the averaged area method, the amount of electricity consumed by the machine per shift is obtained.

Abstract
In this article, were studied sediments in the Mirishkor main canal. Were identified erosion processes resulting from water movement in the main canal with using GIS. Sediment layers in the canal water flow were identified as factors influencing the flow of the sediment through the ArcGIS 9.3 program. One of the main obstacles in the main canals is the analysis of the results of the deposition of suspended particles in the water at the bottom of the canals using geoinformation systems. The dependence of suspended particles in canals on water discharge and canal topography has been partially analysed. In the Mirishkor main canal area sediment washing core equal to an average of 9.2 tons per year, i.e. a potential erosion process is happening in this channel. As a result, the contribution of sediment flow in the canal water increases and causes a number of complications. According to the results, the particles in the upper part of the main channel move depending on the water discharge.

Abstract
Applied lubrication tools come to the brink of their normal effectiveness. A method for reducing the wear of wheels and rails and a design for its implementation, consisting in the application of the proposed differential axis. The predicted comparison criteria depending on the change in the value of the elastic-friction coupling between the wheels, as well as the calculated effect, in comparison with a rigid pair of wheels, indicates the possibility of selecting the optimal coupling between the wheels during operational tests. A numerical assessment of the movement of the model 18-100 trolley in a curve with a radius of 200 m was carried out. Based on the results of a comparative assessment, it was determined that when the trolley with wheelsets moves in differential mode, compared with typical, depending on the amount of coupling between the wheels, the average decreases: lateral force by 20.5–40.2%, and the specific work of the displacement friction forces at the contact points by 26.6%. The criteria for reducing wheel wear along the surface of the ridge and the ridge, as well as the specific wear of the vertical and lateral rail, when the connection between the wheels (to critical to slip) increases, practically do not change and, accordingly, make up 36.8%, 13.2% and 33.5% and 25.5%.

Abstract
The article discusses the problem of increasing the energy efficiency of the 3 kV DC traction power supply system on the railways of the Russian Federation. As one of the ways to amplify it, the authors consider a system of contactless automatic voltage regulation under load of converting units of traction substations, where reactor controlled devices serve as the regulatory body. As one of the directions for improving the system, the use of thyristors in the design of a controlled device is proposed. The article presents the functional diagrams of contactless automatic voltage control systems with thyristor-reactor and thyristor controlled devices, shows the external characteristics of the converter unit with these systems. To calculate the economic efficiency when introducing contactless automatic voltage control systems with reactor, thyristor-reactor and thyristor controlled devices, a methodology has been developed based on calculating the savings in reduced costs, as well as the payback period when replacing a contactless automatic voltage control system under load with a reactor controlled device by a system with thyristor-reactor and system with thyristor.

Abstract
The article discusses the structure of the organization of current repairs of modern locomotives equipped with microprocessor control and diagnostic systems. Based on these sys-tems, remote monitoring of the technical condition of locomotive units has been implemented. The block diagram of the recommendatory nature of the organization of current repairs using diagnostic information is presented. The above algorithm allows predicting the residual life by any of the studied parameters, thereby determining the mileage at the moment of which a fail-ure occurs on some parameter. This gives a huge advantage in preventing incidents, as well as in the long-term planning of repair work on wheel turning and rolling, based on the remaining life. Thus, the well-coordinated organization of current repairs using diagnostic information, allows operational methods to eliminate the faults of the nodes. A recommender structure in the form of a single integrated system for organizing repair cycles will allow establishing links between the involved repair personnel in the form of electronic terminals for notification of the actual technical condition of the locomotive. A program has been developed for calculating the residual mileage of wheel sets for the corresponding types of defects, which also allows long-term planning for turning and rolling of wheel-motor blocks wheelsets, as well as to regulate the overhaul runs of a locomotive.
