摘　　要：基于Adams/Car软件创建汽车半主动悬架系统多体模型,利用改进遗传算法优化模糊规则的策略,实现汽车半主动悬架系统模糊控制器的设计,为了证明模糊控制器的控制效果和遗传算法的优化性能,在Matlab/Simulink环境中对汽车半主动悬架系统多体模型实现联合仿真分析。与被动悬架系统的分析对比说明,基于Adams/Car和Matlab/Simulink软件创建的汽车半主动悬架系统模糊控制器在很大程度上降低了人身加速度、改善车辆的乘坐舒适性和驾驶平顺性,同时也证明了采取联合仿真方法的有效性和准确性。A multi-body model of semi-active suspension system is established based on Adams/Car software,by using the improved genetic algorithm to optimize the fuzzy rule,so that the design of fuzzy controller of the semi-active suspension system is achieved.To testify the control effect of fuzzy controller and the optimal performance of the improved genetic algorithm,a simulation analysis of semi-active suspension system is realized in Matlab/Simulink.After comparing with the passive suspension,which results show that the developed fuzzy logic controller of semi-active suspension system based on Adams/Car and Matlab/Simulink can largely reduce personal acceleration,improve the ride comfort and driving vehicle smooth,meanwhile the validity and accuracy of co-simulation are also testified.
