Occurrence of Torsional Oscillations in Railway Wheelsets

Original language description

The latest achievements in semiconductor electro technology allowed to operate railway locomotives with very high tractive power. Transmission of high torque values to wheels reveals failures in the press-fitted joint between the wheel and the axle that were almost unknown until these days. One of the specific phenomena participating in the creation and developing of fatigue failures are periodically repeating oscillations of running wheelsets, which may appear and compromise the safety of railway vehicles. The article is devoted to simulation of dynamical processes influencing development of such phenomenon that may occur in drives of the vehicles. Models of such processes involve both dynamics in the transmission of the torque to the wheels and the variable external influences (adhesion conditions, track irregularities, variation of wheel forces, etc.), which the running wheel is exposed to. A procedure of creating mathematical model based on the idea of simplified description is proposed and described in the article. Consequent use of such mathematical modelling is described when a Simulink model of a real railway vehicle is designed. In the simulation experiments the Simulink model serves for the parametric analysis of individual components. The model is ready to make an effective design of control for suppression unwanted impacts
