【摘要】 利用ADAMS/Car软件建立了车辆多体动力学模型;基于遗传算法策略设计了主动悬架模糊控制器并通过Matlab编写了控制算法,基于ADAMS/Car和Matlab/Simulink对主动悬架系统进行联合仿真。通过随机路面输入和脉冲路面输入下的仿真结果分析,表明联合仿真的方法正确、可行,同时通过试验结果分析表明,该控制方法能够有效提高汽车的平顺性能。更多还原

【Abstract】 The paper presents the design process of controller for active suspension employed by vehicle based on the co-simulation.Firstly,a detailed multi-body dynamic model of the vehicle was established by using ADAMS/Car software package.Secondly,a fuzzy controller was designed for active suspension system based on genetic algorithm,then programmed by means of Matlab/Simulink.Finally,the cosimulations were carried out based on ADAMS/Car and Matlab/Simulink.The co-simulation model can simulate vehicle dynamic response with the control of ASS under random road and impulse road condition.Through simulation result analysis,it indicates that the co-simulation method is effective and feasible,and the experimental result indicates control method is applicable,too.更多还原
