Study of dynamic loads in the wheel and rail contact influence on the maximum adhesion coefficient

Abstract

A scientific method for estimating the effect of dynamic loads arising at the wheel and rail contacts during locomotive movement is proposed, which most accurately describes the behaviour of a real rolling stock and complies with existing standards on the criteria of vertical and horizontal dynamics, as well as indicators of the movement stability. The dependences allowing illustrating the influence of the coefficient of vertical dynamics and relative horizontal slip on the tractive qualities of a locomotive are obtained.
