Analysis of Occurrence of Torsion Oscillations in Wheel-set Drives Used in Modern Railway Vehicles
Original language description
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 mentioned above. The aim of this work is to describe the ways of the oscillations' occurrence and duration according to the vehicles’ external conditions. The solution of the previously mentioned problem has been solved with the help of 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 wheel-set in the situation when the adhesion is lost. The results describe appearance, duration and disappearance of the oscillations according to variable friction coefficients and other parameters. The results show that variable friction coefficient values lead to the different amplitudes of the torsional oscillations. Other influences are the values of the torque and the geometry of the track.
