摘　　要：通过分析高速万向轴传动式动力车万向轴传动系统的结构,建立了传动系统的扭转振动理论计算模型,特别考虑了万向轴附加力矩的影响,对万向轴传动系统进行了理论分析和数值计算,得到了高速动力车在起动和轮轨粘着瞬时下降后恢复时传动系统的振动响应。结果表明该万向轴传动系统结构合理,不会出现粘滑振动失稳现象。Based on the structure analysis of the universal - shaft driving system of high - speed power car, a torsion vibration model of dri -ving system is set up, specially considering the influence of additional torque of the universal - shaft. In this paper, the vibration responses of driving system under the starting of power car and the descending of wheel/rail adherence instantaneously is achieved. The result indicates that the structure of universal - shaft driving system is reasonable and the unsteadiness of stick - slip vibration doesn' t occur.
