Co-Simulation-Based Verification of Torsional Vibration Protection of Electric-Driven Railway Vehicle Wheelsets

Torsional vibration is an oscillation phenomenon occurring at driven railway vehicle wheelsets. As the resulting dynamic stresses can be significantly larger than maximum static motor torque, axle and press fit are risk of failure. To prevent dangerous events with these, from failure, traction drive manufactures nowadays used to implement suppression algorithms in controls. In this paper, effectiveness such analyzed. Furthermore, as a pilot survey, we analyze what extend controls influence excitation torsional vibration.
