摘要: 悬架作为现代车辆的关键部件之一,对车辆的平顺性有重要影响。基于ADAMS和MAT-LAB软件分别建立了装备主动空气悬架的1/4车体虚拟样机模型及1/4车体主动PID控制模型,并对PID参数进行了整定。通过联合两个模型对某装备可控悬架的车辆进行了仿真分析,结果表明:基于PID控制的主动空气悬架与被动悬架相比,能够减小车辆振动,改善车辆的平顺性。该方法避免了建立车辆系统动力学方程及状态方程,提高了悬架系统的设计效率,同时为复杂机械系统的控制与仿真提供了新方法。Abstract: As one of key parts in modem automobiles, the suspension has great influence on the smoothness of automobiles.Based on the ADAMS and MATLAB method, a 1/4 vehicle air-suspension model and an active vehiclePID control model are established with stochastic road excitation together with the PID parameters definition.Andthe effects of passive control and semi-active control are investigated based on the ADAMS-MATLAB co-simulation.The result shows that the present active control can reduce the vibration of automobile and thus improve the smoothness compared to the passive suspension system.This simulation method improves the efficiency of the suspensiondesign and provides a new way for control and simulation of complex mechanical systems while avoiding buildingtheir dynamical and state equations.
