Abstract

The Purpose of the author of the article is to develop the scientific basis for assessing the work of the railway track under the influence of rolling stock. For this purpose, a modern method has been developed for determining the rational, from the point of view of the technical use of the path, the relationship between the actual operating conditions of the track, the periodicity of the overhauling schemes, and the characteristics of the track design elements. This will be the basis for creating methods and criteria for estimating and forecasting the operation of the track under the influence of the rolling stock, taking into account the durability and the level of safety integrity of the track and rolling stock interaction. Methodology. To achieve the goal, the principles of statistical mechanics, the theory of elasticity and the propagation of the wave process in describing the interaction of a path and a rolling stock are used. Findings.  The concept of detailing the conditions for the interaction of the rolling stock and the railway track as a way of increasing the competitiveness of the railway transport is proposed. To solve the problems of the need to establish interrelations between the technical and economic aspects of railway transport facilities, a concept is proposed to ensure the completeness of the safety of the railway track design during the service life. The criteria providing interrelation between technical and economic aspects are introduced and the algorithm of a method of an estimation of deformative work of a way on parameters of interaction of a way and a rolling stock is offered. Originality. Modern requirements of the competitiveness of railway transport motivate the development of new approaches to ensure the interrelation between the technical and economic aspects of the operation of railway transport facilities. On the basis of such approaches, the cost of safe operation of the railway infrastructure is minimized taking into account the actual operating conditions. The paper proposes the basic principles of railway track work evaluation for the deformative work of the track under the action of the rolling stock, as the basis for classifying the technical conditions of the railway track corresponding to different degrees of reliability. Practical value. One of the main factors of the impossibility of providing the interrelation between the technical and economic aspects of the operation of railway transport objects is the lack of knowledge about the relationship between the technical states of the elements and the railroad construction, the operating conditions and the periodicity system of the overhauls at the operational stage of its life cycle. This factor requires the introduction of new approaches, criteria and methods of evaluation. Therefore, the proposed concept of detailing the conditions for the interaction of the rolling stock and the railway track, the criteria for the deformative work of the elements and the design of the track, as well as the method for estimating the deformative work of the track in terms of the interaction parameters of the track and the rolling stock allow us to investigate the interrelation of the technical and economic aspects of the operation of railway transport facilities.
