摘　　要：基于AMESim软件建立1/4空气悬架系统模型,利用Matlab软件设计空气悬架系统控制器,使用Matlab和AMESim对空气悬架系统进行联合仿真。白噪声路面信号输入下的联合仿真结果分析表明,安装主动空气悬架系统车辆的最大振动加速度与振动加速度均方根、平均车身高度、动载荷均比安装被动空气悬架系统的车辆小,该仿真结果符合有关主动空气悬架系统的一般研究结论,该控制方法可以有效提高车辆的平顺性。A 1/4 ECAS model is established by using AMESim, a PID controller is designed for active suspension system based on Matlab, and the co-simulation are carried out based on AMESim and Matlab/ Simuhnk. Simulation analysis of the white noise road condition shows that the maximum vibration acceleration and root-mean-square of vibration acceleration, the mean vehicle height and dynamic load of a vehicle with active air suspention is lower compared to the vehicle with passive air suspention. The simulation result conforms the conclusion of generatl studies on active air suspention. The control method is effective to improve running smoothness.
