| 摘 要： | 为了改善汽车行驶的舒适性、安全性并减小轮胎动载对路面的破坏,以某载货汽车的四自由度悬架系统为研究对象,将车速分别为50、80和100km/h在A、B和C级路面行驶的车身垂直加速度、前后轮胎动载荷的统计均方根值作为目标,用多目标遗传算法和多标准决策方法进行了优化.结果表明:车身垂直加速度均方根值平均减小了40%,前后轮动载荷均方根值平均减小了30%,性能有较大改善,并且采用后期多标准决策方法,可以同时求得满足不同设计需求的最优解,较传统多目标优化方法更为实用有效.

| Abstract: | For improving automobile ride comfort,safety and decreasing tire dynamic load to road,the four degree of freedom suspension model was established.MOGA(multi-object genetic algorithm) and multi-criteria decision method were applied to multi-objective optimization of suspension parameters,with root-mean-square values of vertical acceleration of body,front and rear tire load at 50,80 and 100 km/h on A,B and C level road as objective functions.The results show that on average,root-mean-square value of vertical ... |
