| 摘 要： | 利用多体动力学技术和联合仿真的方法及半主动开关控制和改进型开关控制中的时滞,对车辆动力学性能的影响进行了仿真分析.结果表明:无时滞理想状态下,半主动控制对车辆横向动力学性能的控制效果明显,且运行速度越高控制效果越好;时滞对车辆横向动力学性能的影响较大,但并非随着时滞的增大而逐渐恶化,而是呈波浪形起伏,当时滞处于100~200 ms和400~500ms范围时,半主动控制效果最差,甚至失效;考虑时滞后,开关控制效果优于其改进型,这与没有考虑时滞因素时结论相反,证实了时滞分析的必要.

| Abstract: | The influence of time delay on railway vehicle dynamic performance were analyzed in semi-active on-off control and improved on-off control by using multi-body dynamic technology and co-simulation method.The results show that the effect of semi-active control on vehicle lateral dynamic performance is obvious, and the higher vehicle speed,the better performance in ideal condition without time delay.Although the effect of time delay on lateral dynamic performance is large,it is not worsened gradually with time... |
