Abstract
This article considers the coefficient of friction between the brake shoe and the wheel of the railway rolling stock. It conducts a review of the works on the study of the interaction of the brake shoe and wheel, considers a method for obtaining the calculated value of the friction coefficient used in the Russian Federation and in many countries, and indicates a drawback of this method that leads to errors in the calculations. The paper specially focuses on the study of heating of brake shoes during braking as a factor in changing the coefficient of friction between the wheel and the brake shoe. The FEM model of heating the brake shoes during braking is constructed taking into account changes in the mass and shape of the brake shoes during wear. Brake shoe wear is considered as a factor in changing the effectiveness of train brakes.
