摘　　要：为提高车辆乘坐舒适性,基于采用典型算法的车身加速度幅频特性分析,提出了基于车身速度和加速度信号联合反馈控制的半主动控制算法。以天棚半主动控制作为参照,对该算法的性能进行了分析和评价。结果表明,该算法能够实现对车身加速度、悬架挠度和车轮动载荷等悬架性能指标的有效控制,在大幅提高车辆乘坐舒适性的同时改善了操纵稳定性。算法简单实用、计算量小,适用于车辆悬架系统的振动控制。In order to improve the ride comfort of vehicle, a semi-active control algorithm based on the as- sociated feedback control of vehicle body＇s velocity and acceleration is proposed based on the analysis on the amplitude-frequency characteristics of vehicle body＇s acceleration with typical algorithms. Then with sky-hook semi-active control algorithm as reference, the performance of control algorithm is analyzed and evaluated. The results show that the control algorithm proposed can achieve effective control on suspension performance indicators such as the acceleration of vehicle body, the dynamic deflection of suspension and the dynamic load of tires, and hence improve both the ride comfort and the handling stability of vehicle. The algorithm is simple and practical with less computation efforts required, suitable for the vibration control of vehicle suspension system.
