摘　　要：以某轿车模型为研究对象,采用虚拟样机技术,使用Adams/Car软件建立了车辆多体动力学模型;基于模糊控制策略设计了主动悬架模糊控制器并通过Matlab/Simulink创建了主动悬架模糊控制器模型。利用Adams/car和Matlab/Simulink对装有主动悬架系统的整车进行随机路面输入和脉冲路面输入的联合仿真分析。仿真结果表明采用模糊控制的主动悬架系统比被动悬架更能够显著降低轮胎动载荷、悬架动挠度和车身垂向加速度,一定程度上改善了汽车的行驶平顺性和操纵稳定性。Taking a car model as the research object, using virtual prototype technology, using the software of Adams/car vehicle multi-body dynamics model is established. Based on the fuzzy control strategy of active suspension fuzzy controller was designed and create the active sus-pension through Matlab/simulink model of the fuzzy controller. Using Adams/car and Matlab/simulink affect the vehicle active suspension system with random road input and input pulse pavement joint simulation analysis. Simulation results show that fuzzy control of active sus-pension system is better than passive suspension can significantly reduce the tyre dynamic load, body vertical acceleration, suspension dynamic deflection and to some extent, improved the riding comfort and handling stability of vehicles.
