| 摘 要： | 针对孟买地铁车辆,运用刚柔耦合的车辆振动模型,研究弹性车体与构架耦合振动,分析车体弹性对平稳性的影响。分析表明,车体刚度越大,车体弹性对平稳性的影响越小;随着转向架一系垂向刚度的增加,构架的浮沉频率会逐步增加;通过参数优化,当构架浮沉频率与车体垂向一阶弯曲频率相近时,不会发生车体垂向弯曲共振现象。

| Abstract: | In view of Mumbai metro vehicles,with the application of rigid-flexible coupling vehicle vibration model,the resilient carbody and frame coupling vibration is researched,the effect of the carbody resilience on ride comfort is analyzed. The analysis shows that,the bigger carbody stiffness is,the smaller effect of carbody resilience on stability will be; with the increase of primary vertical stiffness of bogies,the bouncing frequency of the frame will increase gradually; By optimization of parameters,when the... |
