摘要：

The present work, regarding the stick-slip phenomena, takes into account the real shape of the friction coefficient characteristic. In the literature, this characteristic was represented by piecewise interpolation. The study in this paper is based on analytical interpolation with a single exponential function and integration of nonlinear equations of motion using the Simulink toolboxes. There are presented the conditions of stick-slip occurrence and its influence on the variables that define the motion. Moreover, there are pointed out that in the wheelset occur dynamic loads which have adverse effects on both strength and traction vehicle performance.
