摘　　要：设计了以簧载质量垂向速度、簧载质量俯仰角速度及其变化率作为模糊控制器输入的控制策略,基于该双模糊控制器的车辆半主动悬架能够综合改善车辆的垂向和俯仰振动。以某型车半车悬架模型作为研究对象,对采用双模糊控制器控制的半主动悬架系统进行了计算机仿真分析。仿真结果表明,采用双模糊控制器控制策略能较好地改善车辆乘坐舒适性,达到综合减振效果。The control strategy is designed, which vertical velocity and pitch angular velocity of sprung mass, and their change rates are chosen as the inputs of fuzzy controllers. Vehicle semi-active suspension based on the double fuzzy controllers can improve both vehicle vertical and pitching vibration comprehensively. A semi-active suspension model of one vehicle is chosen as the research object, and the double fuzzy control strategy is used in the vehicle semi-active suspension system to conduct computer simulation analysis. The results of simulation demonstrated that the double fuzzy control strategy could improve the ride comfort better, and reached comprehensive effect of improving vibration.
