  • In order to investigate the stability of drive system under torsional-longitudinal coupling vibration for locomotive in slippage process, a dynamics model of drive system with single wheelset was set up, the torsional and longitudinal vibration freedoms of the wheelset were taken into account. The nonlinear differential equations of drive system vibration were linearized at the balance point, and its eigenvalues were calculated to judge the stability of the system, whose critical vibration curves were gained. Analysis result shows that the torsional vibration of drive system and the longitudinal vibration of wheelset are self-excited vibrations because of the negative slope of adhesion curve between wheel and rail, and their stabilities depend on wheelset's speed and axle load. The higher the velocity is and the lower the axle load is, the stabler the vibrations are. So the damps of torsional and longitudinal vibrations are able to suppress the unstable vibrations.
