摘　　要：在对电流变减振器的研究基础上,使用电流变减振器作为控制元件组成相对模糊控制半主动悬架系统,运用计算机仿真对车辆悬架进行研究。仿真结果表明,相对模糊控制半主动控制算法能有效地控制车身的垂直加速度,从而能提高车辆的舒适性和平顺性。A relative fuzzy semi-active control suspension system in which the ER dampers are used as the semi-active control actuators has been proposed and developed based on the analytical of the ER damper. The simulation are conducted to characterize the dynamical performance and to develop semi-active control technology of relative fuzzy semi-active suspension system based on the ER damper. Simulation results demonstrated that relative fuzzy semi-active control methods can effectively control the body acceleration and improve the ride comfort and the handling characteristics.
