Bondarenko I. Development of the scientific basis for evaluate the work of the railway track under the influence of rolling stock

The work is aimed at improving the methods of assessing the operation of the track under the influence of rolling stock. Owing to the formalization of concepts and criteria of deformation work, a method for the theoretical evaluation of the deformation work of the track has been developed in terms of the interaction parameters of the track and the rolling stock. It allows to investigate the relationship between the actual operating conditions of the track, the frequency of the overhauling schemes and the technical conditions of the elements and the design of the track. As a basis for the classification of railway track reliability, a new system of evaluation terms for technical conditions of the track for reliability states has been developed. The method for determining the parametric data of the propagation of the interaction of the track and the rolling stock (based on the description of the process of propagation of the load pulse by power waves in the design of the path in time, taking into account the reciprocal reaction of the elements on them) is new, and allows to solve problems in the design and content of the railway durability and completeness of safety.
