摘　　要：基于双横臂扭杆独立悬架的实体建模之上建立了其有限元模型,对各零部件之间的连接关系进行了模拟,并在此基础上进行了静态强度特性分析,得到了引起车架纵梁产生开裂原因的结果。对双横臂扭杆独立悬架进行了结构优化,结果表明优化后的结构克服了车架纵梁开裂的问题并得到了应用,对工程有一定的实用价值。Based on the noumena model of Double-Torsion bar and Double-wishbone Independent Suspension,the finite element is erected.It has analysed the static intensity of Independent Suspension by simulating the connection among the parts and acquired the reason why the Frame Side Rail could crack. The structure of Double-Torsion bar and Double-wishbone Independent Suspension is optimized,which showed the structural improvement conquered the question why the Frame Side Rail could crack.The structural improvement has been used,which provided reliable value for engineering.
