Abstract
The process of operating vehicles determines the interaction of the wheel and rail. Traffic safety and the main technical and economic indicators of track management and rolling stock largely depend on these parameters. The result is the effect arising from the rolling friction and especially from the friction of the wheel sliding on the rail during braking, relative to these changes there is a significant increase in the intensity of wear of the wheels of the rolling stock, which, in turn, can lead to catastrophic results for the locomotive industry. Also, in the process of operation of the rail in most cases, defects are formed that have the character of a complicated state: its head is subject to wear, crumpling, cracking and buckling, contact fatigue damage can develop in the metal.
