摘　　要：以二自由度半车模型作为研究对象,用Matlab/Simulink软件建立汽车悬架动态模型,并建立了汽车悬架参数智能匹配系统,以车身振动加速度、车身振动位移作为评价标准,在时域内对软件模型做了运动仿真模拟,通过观察并分析加速度和位移响应变化曲线,从而评判汽车的平顺性与安全性,最后得到新匹配的性能相对比较优良的悬架系统。Taking two and half degrees of car model as the research object, this paper uses Matlab/Simulink software to build dynamic suspension model of the vehicle and the intelligent matching system of automatic suspension parameters, and uses auto body acceleration and body vibration displacement as the evaluation criteria, meantime simulate the software model in the time domain. Through observation and analysis of the acceleration and displacement response curve, this system can evaluate the riding comfort and safety. Finally, a new matching performance of the suspension system is obtained.
