摘　　要：以二自由度车辆主动悬架模型为研究对象,基于车辆动力学理论,建立主动悬架系统的动力学方程和路面输入模型方程,并以悬架动挠度为控制目标设计模糊控制器。在Matlab/Simulink里建立二自由度主动悬架系统模型和随机路面激励模型,结合模糊控制器进行仿真分析。结果表明,相对被动悬架而言采用以悬架动挠度为控制目标的模糊控制策略的主动悬架能有效地抑制车辆振动,提高车辆的乘坐舒适性和安全性。Based on the vehicle dynamics theory,the 2-DOF active suspension model was studied to establish its dynamic model and the road model.Besides,the fuzzy controller were designed with dynamic deflection of the suspension as the controlling object.The 2-DOF active suspension model and the stochastic uneven road model were established in Matlab/Simulink in combination of the fuzzy controller to simulate the performance of active suspension.The results show that the active suspension can effectively suppress vehicle vibration,and improve the riding performance and security.
