摘要:
基于某设计运行速度为120 km/h的新型地铁车辆，利用SIMPACK多体动力学软件对转向架进行建模，仿真分析磨耗轮状态下、车辆在安装抗蛇行减振器前后的临界速度。使用机车车辆滚动振动试验台对该型转向架进行滚振动力学试验，并对比在安装抗蛇行减振器前后车辆的稳定性。研究结果显示，在车轮磨耗状态下，安装抗蛇行减振器时的车辆蛇行临界速度高于160 km/h，不安装抗蛇行减振器时的车辆蛇行临界速度低于120 km/h。这说明安装抗蛇行减振器能够显著提高车轮磨耗后车辆的稳定性。
Abstracts:
Based on a new metro vehicle with design speed of 120 km/h, the multi-body dynamics software SIMPACK is used to model the bogie, and the critical speeds of the vehicle before and after installing yaw damper under the condition of worn wheel is simulated and analyzed. The rolling vibration dynamics test of this bogie is carried out on the rolling vibration test rig, and the vehicle stability before and after installing yaw damper is compared. Research results show that under the condition of wheel wear, the critical speed is higher than 160 km/h when yaw damper is installed; when the yaw damper is not installed, the critical speed is lower than 120 km/h. It is proven that the installation of yaw damper can significantly improve vehicle stability after wheel wear.
