Abstract
Based on the data obtained by calculating the curvature and radius of the worn profile, as well as the angles of inclination of the tangent to it at different rolling, a refined wear model is considered. For this purpose, additional wear graphs are constructed according to the rolling profile, taking into account the very complex nature of the wheel and rail contacting surface wear at different locations of the reference points. Calculation errors are estimated, calculated parameters such as wear at various points are corrected. For further research of the theoretical nature, analytical expressions are used, on the basis of which graphical dependencies are constructed. The calculations are performed using the finite difference method, and the calculation error is estimated. Along with this, a tabular method of presenting a significant amount of data was used. The published article will be useful for understanding the complexity of the processes and quantifying the interaction between the wheel and rail in contact.
