摘要
为了研究减少高速列车运行中车体横向振动,利用ADAMS/Rail与Matlab建立了联合仿真高速列车车辆动力学模型,并利用开关型天棚控制算法和连续型天棚控制算法对高速列车车辆横向减振器进行了半主动控制仿真研究.结果表明:开关型天棚控制算法简单实用,但控制效果逊于连续型天棚控制算法,还有可能发生颤振;连续型天棚控制算法控制效果好,但对系统的实时性和减振器结构的要求较高.针对这2种控制器的优缺点,同样基于上述模型,结合模糊理论和天棚速度阻尼控制,开发了一种新的控制方法,经研究表明,该控制方法具有很好的控制效果,并能弥补上述2种方法的不足.
For the purpose of attenuating the vehicle body lateral vibration, dynamics combined model of high-speed railway vehicle was established by using ADAMS/Rail and Matlab. The on- off and continuous sky-hook method applied to lateral damper was simulated based on the combined model. The results show that the switchable sky-hook method is simple and practical, but it may induce the chatter of the system and the result is inferior to continuous sky-hook method. The con- tinuous sky-hook method has the better result in attenuating the vibration of the railway vehicle body, whereas, this method require the complicated damper structure and more real-time system. Considering this two method＇s advantage and shortcoming, the fuzzy sky-hook method was put forward which was also based on the combined model. The research show that this method not only has excellent control re- sult, but also can make up the disadvantage of the two methods mentioned above.
