At various stages of the development of railway transport, various problems of interaction between the wheel and the rail came to the fore. These include mechanical fatigue of rails and contact fatigue of wheels and rails, their increased wear, which leads to violations of traffic safety, and in particularly neglected cases to the descent of rolling stock. In practice, to determine the cause of destruction and wear, three components of the interaction force are investigated: vertical, horizontal and longitudinal. The problem of intensive wear of wheels of rolling stock and rail threads was faced by railway transport workers in the first relatively recently. This problem manifests itself especially in areas where the curves of a small radius of the railway track are located.
This work is aimed at studying the interaction of a rolling stock wheel and a rail track and the resulting interaction of transverse forces in the longitudinal direction. The article considers the change in lateral force depending on the size of the irregularity in the plan. The influence of this force on the formation of lateral wear and the defects that this wear leads to is definitely determined. A computer simulation was carried out in the "Universal Mechanism" environment in order to determine the relationship between the amount of irregularity in the plan and the rate of change of transverse forces. The problems related to the interaction of the rolling stock wheel and rails affecting the formation of defects in the rail chain and wheel are considered.
