摘　　要：文章根据汽车传动系扭振动力学方程,建立了传动系扭振仿真模型,在此基础上进行仿真分析,并通过实车试验加以验证,通过仿真运算,观察到传动系中存在较明显的扭振成分;对仿真模型中的参数进行灵敏度分析,得出对扭振影响较大的参数,通过对相应参数的修改,使得扭振降低,该方法为解决车辆传动系扭振提供了参考依据。According to the torsional vibration dynamics equation of the vehicle transmission,a simulation model of the torsional vibration is established.The simulation analysis of this model is conducted and the actual vehicle tests are performed to verify the model.The simulation results show the existence of obvious torsional vibration in transmission system.The parameters which have great influence on the transmission system are obtained by the sensitivity analysis of the model parameters.The torsional vibration can be weakened by modifying these parameters.The presented method provides a new reference for solving the problem of vehicle transmission torsional vibration.
