高速列车抗蛇行减振器故障分析
|
摘要
基于动力学软件SIMPACK建立了我国某高速列车动力学计算模型,仿真分析了抗蛇行减振器在失效故障下对高速列车动力学性能的影响,对实际分析高速列车故障有一定指导作用,具有一定工程应用价值.分析表明:每辆车失效1根或2根抗蛇行减振器对车辆稳定性、平稳性、安全性影响不明显;每辆车的外侧抗蛇行减振器失效时,对稳定性影响非常大,对平稳性及安全性影响不明显;每辆车抗蛇行减振器全部失效时,对稳定性、平稳性、安全性影响都非常明显.
It is analyzed that effect of troubles in yaw damper on vehicle dynamic performance of highspeed vehicle based on SIMPACK.It has some engineering application value on trouble analysis of highspeed vehicle.It could be concluded that it has less influence on vehicle dynamic performance as existing one or two disabled yaw dampers.As all outside yaw dampers don't work,stability deteriorates sharply and riding quality and safety has less change.Meanwhile,it has a great significance on stability,riding quality and safety as all yaw damper don't work.
