中文摘要：
基于减振器简化等效模型分析了某动车组车辆系统动力学性能随抗蛇行减振器安装刚度不同的变化情况，并且比较了考虑构架结构弹性振动对这种变化的影响。结果表明，抗蛇行减振器安装刚度对车辆系统动力学性能具有一定影响，尤其是当车辆运行速度达到250km／h时影响较大；此外，构架的弹性振动也影响着抗蛇行减振器安装刚度的选择。
英文摘要：
Based on simplified equivalent model, vehicle dynamics performance of a certain EMU changed along with anti-yaw damper mounted stiffness was analyzed, influence to which produced by elastic vibration of the frame was considered. The results show that dynamics performance of vehicle system is affected by changes of anti-yaw damper mounted stiffness, especially when the vehicle running speed reached 250 km/h; Moreover, elastic vibration of the frame influence the choice of mounted stiffness.
