摘要
针对被动悬挂不可控、半主动悬挂不能主动出力和主动悬挂耗能过大等问题,提出基于电磁作动器和磁流变阻尼器相复合的电磁悬挂结构方案。依据军用车辆能量回收潜力和行驶性能与射击精度对悬挂控制的要求,提出采用分档控制方法的基于行驶工况与作战效能的振动控制策略。分析表明,该电磁悬挂具有Fail-Safe功能,增加了参数的可调范围,在分档控制策略下能够实现车辆振动的被动、半主动和主动控制,并能在a档和b档时采用电磁馈能实现振动能量的部分回收,适用于军用履带战斗车辆振动控制需求。
As the passive suspension is uncontrollable,semi-active suspension can not give force out actively and active suspension costs excessive energy,a novel electromagnetic suspension structure is proposed in this paper with the hydraulic shock absorber replaced by MRD,and EA with the traditional spring element in parallel is adopted.Based on energy reclaiming potential for military vehicles and requirements of driving performance and shooting accuracy, a subsection vibration control algorithm is put forward. Analysis results show that the novel electromagnetic suspension structure has a Fail-Safe function,and could increase the range of the suspension adjustable parameters,and could perform the passive,semi-active and active control and the vibration energy could be reclaimed under in certain conditions.
