| 摘 要： | 为减少车辆悬架系统开发周期和成本，利用SIMPACK软件建立了车辆1／4悬架多体动力学模型，基于天棚控制策略设计了半主动悬架控制器，并通过MATLAB／SIMULINK编写了控制算法对其进行联合仿真．将采用半主动悬架系统得到的仿真结果与采用被动悬架系统得到的仿真结果进行了对比，车身垂直加速度均方根值减少了30．2％．结果表明，基于天棚控制的半主动悬架可以有效衰减车身的振动，改善车辆的行驶平顺性，从而为车辆动力学系统的仿真分析提供了一种有效方法．

| Abstract: | In order to shorten the cycle and save the costs of the development of the vehicle suspension system, a 1/4 vehicle suspension model was established by using SIMPACK software package. A skyhook controller was designed for the semi-active suspension system and worked out by means of MATLAB-SIMPACK co-simulation. Compared with the passive suspension, the semi-active suspension based on skyhook control strategy could reduce the mean square roots of the vertical acceleration by 30. 2 %, and the semi-active suspension had the ability of reducing the vehicle＇s vibration and improving the suspension ride comfort. The co-simulation also offered an effective method for the simulation of complex dynamic systems. |
