摘　　要：以天棚控制方法为理论基础,结合磁流变减振器的工作机制,建立了磁流变半主动悬架硬件结构系统,并通过在实车试验平台上实验分析了被动悬架和磁流变半主动控制悬架的平顺性。结果表明,相比于被动悬架,磁流变半主动悬架能够很好地抑制低频段车体垂直方向的加速度变化和振动幅值,从而提高车辆平稳性和舒适性。Based on the sky-hook control method,this paper established the magneto-rheological semi-active suspension hardware structure combining with the working mechanisms of the magneto-rheological shock damper. The ride comfort of passive suspension and semi-active suspension was analyzed on real vehicle experiment platform. The results show that compared with the passive suspension,semi-active suspension can restrain change of the acceleration in the vertical direction and vibration amplitude in the low frequency of vehicle body. Thus semi-active suspension can improve vehicle stability and comfort.
