车辆悬架磁流变阻尼器动态响应及影响因素分析
|
摘要
在驱动器、阻尼器和被控系统等不同层次的动态响应研究范畴,指出了阻尼器动态响应的研究内容及方向;根据车辆悬架磁流变阻尼器的实际运行特点,提出了动态响应的合理描述,并探讨了阻尼器动态响应测试研究的若干重要问题;最后,分析了磁流变阻尼器动态响应的影响因素,为提高磁流变阻尼器动态响应性能指出了研究方向。
Dynamic response is extremely important for Magneto-rheological (MR) damper,and directly affects the MR damper performance in semi-active control system. The dynamic responses for driver,damper and the whole controlled system are discerned,and the research contents and directions of dynamic response of MR dampers are also indicated. Based on the operation characteristics of MR dampers for automotive suspension,a reasonable description of dynamic response is proposed,and some important issues for dynamic response testing are discussed. Finally,the influence factors upon the response time of the MR dampers are investigated,and the directions for further improvement are given.
