Rationale: Development of string rails with low weight per meter and high-performance characteristics that determine durability, wear resistance, reliable grip of vehicle wheels to the rail rolling surface is a vital task. Objective: to investigate impact of the geometric parameters of the steel wheel and the flexible string rail with a polymer coating on the performance characteristics; to choose the most optimal parameters of the contact pair wheel-rail. Methods: The calculation was made using the ANSYS finite element analysis software package. Results: in order to reduce the level of contact pressures, it is more expedient to lower the load on the wheel or increase the width of the contact, rather than to increase the radius of the wheel; the most optimal is the contact pair, where the modulus of elasticity of the polymer rail head is equal to the modulus of elasticity of the wheel material, that is, materials similar in elasticity are used in the contact pair.

The article is devoted to the peculiarities of taking into account natural and climatic conditions when designing a highway. It is shown that environmental conditions directly affect the specifics of the designed roads. However, they can play a dual role: both to promote and counteract the long service life of the roadbed. Since it is impossible to influence the weather conditions, it is necessary to provide full protection of the highway. All factors affecting the road condition at the early stages of design were analyzed. It is concluded that if the regulatory and technical requirements are not met, the quality and safety of the road will not be ensured for each road and climate area.in this regard, the most effective methods of protecting and reducing the negative effects of environmental impact were considered.

Background: the determination of the energy indicators of the traction power supply system based on the train schedule in the conditions of operation of storage devices is based on the solution of a number of instantaneous schemes, each of which corresponds to the established operating mode. These methods require adaptation to account for non-linear characteristics or indicators, the value of which is associated with the retrospective of the change. In this regard, it is necessary to use calculation methods based on the solution of differential equations to solve problems related to the assessment of performance in transient or emergency modes, taking into account dynamic characteristics. Modeling the operation of storage devices in the traction power supply system allows you to evaluate the change in indicators depending on the parameters of the devices, traction load and circuit solutions for various topologies. Aim: to determine the structure of models of electric power storage devices in DC and AC traction power supply systems, to consider the results of calculating the main energy indicators, to determine ways to improve circuit solutions based on the identified features, to determine the technical requirements for electric power storage devices in traction power supply. Materials and Methods: to obtain the results, methods for solving differential equations corresponding to various variants of the topology of storage devices in traction power supply, implemented in the Matlab software package, are used. Results: the results obtained allow us to determine the structure of storage devices for traction power supply, evaluate models of devices for traction power supply of direct and alternating current, outline the prospects for further research in the field of circuit solutions and required device parameters. Conclusion: the results of the study allow models of electricity storage devices and technical solutions for their implementation aimed at introducing DC and AC traction power supply into the system.

Background: The paper discusses the features of building a control system for an electro-magnetic suspension of a cargo platform. The operating conditions of cargo systems are associated with a large range of changes in the mass of the cargo and an abrupt change in the voltage of the power source. The control structure of the electromagnetic suspension system contains a non-linear unstable object (electromagnet). This greatly complicates the management process. Aim: The aim of the work is to study the properties of an unstable control object for its representation by an equivalent linear model, which makes it possible to automate the process of controller synthesis in the MATLAB software environment. Methods. The main research methods are computer modeling, computational studies, analysis of research results. Results: An approach to the construction of an adaptive control system for an electromagnetic suspension based on the synthesis of a linear controller based on an equivalent linear model of an unstable object is proposed. Conclusion: The practical significance lies in the fact that the proposed approach can be used to design a control system for the electromagnetic suspension of a cargo platform.
