摘要
仿真研究主动悬架改善重型车辆的平顺性和对路面的损伤。在主动悬架最优控制中采用了相对自由度状态向量,控制更容易实现;建立重型车辆装载主动悬架或被动悬架时的动力学模型,计算车辆路面作用力、车体加速度的统计特性,并加以比较。重型车辆装载预瞄全状态反馈主动悬架后与原被动悬架相比,对路面损伤降低了23%～27%,尤其是车辆平顺性改善了90%以上。
The improvement of heavy vehicle′s compliance and pavement′s damage by use of the equipment of active suspension is studied. Relative freedom state vector is used to study heavy vehicle active suspension′s optimal control theory, and makes control easier. The dynamic model of vehicle with active or passive suspension is created, the statistic characterisfics of the force between vehicle and pavement and the accelerator of vehicle body is computed and compared. Through simulation, compared with the passive suspension, when heavy vehicle is equipped with previewing full state feedback active suspension, road damage level decreases by 23% to 27%, and compliance increases more than 90%.
