摘　　要：应用多体动力学软件建立某铰接式转向架动车组动力学模型,根据应用实际工况,对比分析了直线工况、曲线工况、小半径S曲线、通过三角坑等情况下铰接式转向架车辆动力学性能。研究结果表明,铰接式转向架车辆具有良好的曲线通过能力和优秀的线路扭曲适应能力,而且铰接式转向架轮对对应动力学指标与前后端独立转向架相差较小。直线工况下其运行稳定性满足标准,能够达到设计要求。An articulated bogie EMU vehicle dynamic model was established,and in the analysis of curving performance,stability indices,ride index,the difference of dynamic performance of articulated bogie vehicle was analyzed.The results show that articulated bogie vehicles have better curve passing ability and excellent line twist adaptability.Corresponding dynamic indicators of the articulated bogie are relatively small compared to the front and rear independent bogies.Its running stability is slightly worse under straight linear conditions,but still meet the design requirements.
