摘　　要：由于转型升级的需要,某大型矿用车的前悬架拟由烛式改为双叉臂式,悬架形式的改变对轮胎磨损与平顺性的影响状况被生产企业和用户单位所关注,为此采用仿真研究。首先利用Solidworks和Adams/Car建立双叉臂悬架模型;其次对前悬架硬点参数进行DOE分析;再次采用灰色关联分析TOPSIS法选出综合贡献度最高的6个硬点参数作为优化变量;然后使用Isight中的NCGA算法进行多目标优化;最后采用优化后的悬架结构建立整车模型验证其对整车平顺性的影响状况。改进的结构在减少轮胎磨损的同时保持很好的平顺性。Due to the need of transformation and upgrading,the front suspension of a large mining vehicle is proposed to be changed from candle type to double-wishbone type,and the impact condition of the change of suspension form on tire wear and smoothness is concerned by the manufacturer and user units,for which simulation study is adopted.Firstly,the double wishbone suspension model was established using Solidworks and Adams/Car;Secondly,DOE analysis was performed on the front suspension hard point parameters;Again,the six hard point parameters with the highest comprehensive contribution were selected as optimization variables by using the grey correlation analysis TOPSIS method;Then the NCGA algorithm in Isight was used for multi-objective optimization;Finally,the optimized suspension structure was used.The whole vehicle model was established to verify its influence condition on the smoothness of the whole vehicle.The improved structure maintains good smoothness while reducing tire wear.
