| 摘 要： | 为分析侧向风对高速客车操纵稳定性的影响,以多体动力学为基础,在ADAMs/Car专业模块中建立了某型号高速客车模型.通过考虑车身上7个离散的侧风作用点,进而实现了风压中心漂移的侧风模型.通过对美国ESV规范中规定的侧风敏感性试验标准的改进,分别进行了计及风压中心漂移侧风实验(testl)、风压中心固定下的侧风仿真试验(test2)、无侧风环境下客车高速直线行驶仿真试验(test3),将三者的仿真试验结果进行对比,认为风压中心漂移的仿真数据更为合理,为改善该车型的侧风稳定性提供了参考依据.

| Abstract: | Based on multi-body system dynamics,the model of Yutong high-speed bus was built by the ADAMS/Car software to analyse the influence of crosswind on the high-speed bus handing stability.Seven discrete wind pressure centers that affect the chasis were taken into account,so the crosswind model with a shifting pressure center was achieved.After improving the standard of the crosswind sensitivity test that prescribed by American ESV(Experimental safety vehicle),the crosswind simulation tests with pressure center... |
