Currently, the economy of the Republic of Kazakhstan is adapted to market conditions. Therefore, the current stage of economic development in our country is accompanied by the construction of unique facilities. An example of this is the construction of modern railway tracks, unique bridge structures stretching for many kilometers, etc. The most common is rolling stock used in difficult natural and climatic conditions in various fields and industrial facilities, in the field of construction and utilities. The railway track and rolling stock represent a single thermodynamic system that interacts and depends on each other. The main task of studying dynamic processes in the Rolling Stock-Railway system is to determine the optimal values of this system (overall dimensions, weight, stiffness, coefficients of viscous friction, etc.), which reduce fluctuations and dynamic forces that negatively affect the reliability and strength of rolling stock and road structures.
