Abstract
In order to investigate the self-excited torsional vibration of locomotive drive system, the train adhesion mechanism and a single wheelset model are analyzed. Dynamic equations of the locomotive traction and the torsional vibration of locomotive drive system are established. MATLAB/SIMULINK is used to build the simulation model. The simulation results indicate that the self-excited torsional vibration will occur when the initial slip velocity is located at the descending slope of the adhesion coefficient curve. The principle of energy conservation is used to analyze the mechanism of the self-excited vibration.
