Analysis of occurrence of torsion oscillations in wheelset drives used in modern railway vehicles

Popis výsledku v původním jazyce

This text has been created in the context of the occurrence of the press-fitted joints failure in some running railway vehicles. This work deals with an idea of occurrence of the torsional oscillations in the vehicles' drives that can lead to the problem as previously mentioned. The aim of this work is to describe the ways of the oscillations' creation and duration according to the vehicles’ external conditions. The solution of previously mentioned has been made via MATLAB Simulink and Simpack software simulations. There was created a dynamic model of the vehicle, which is respecting the mechanical and the electrical part of the vehicle. The results of the model are the time dependent oscillations' courses of the wheelset in the situation when the adhesion is lost. The results describe creation, duration and disappearance of the oscillations according to variable friction coefficients and other parame-ters. The results show that variable friction coefficient values lead to the different amplitudes of the torsional oscillations. Another influence are the values of the torque values and vehicle passing through a curve
