摘　　要：汽车下摆臂作为车辆悬挂系统中的重要组成部分,主要支撑车身和减震器,并缓冲行驶中的振动。本文以某汽车麦弗逊悬架下摆臂为对象,首先利用ANSYS建立有限元模型,分析其在前行制动、极限转弯、前行冲击和倒车冲击四种极限工况下的强度,然后对其进行拓扑优化,优化目标函数为汽车下摆臂体积最小化,最后对优化后的结果进行强度校核,结果显示,优化后的下摆臂质量减小,强度满足要求,证明此方法的技术有效性,为支架类零件的设计提供参考。As an important part of the vehicle suspension system,the vehicle hem arm mainly supports the body and shock absorber,and buffers the vibration during driving.Taking an automobile McPherson suspension lower arm as an object,First,the finite element model was established using ANSYS to analyze its strength under four extreme conditions of forward braking,extreme turning,forward impact and reverse impact.And then the topology optimization was carried out,the optimization objective function is to minimize the volume of the vehicle hem arm.Finally,the strength of the optimized results is checked.Result shows that the mass of the optimized hem arm is reduced and the strength meets the requirements,which proves the technical effectiveness of this method and provides a reference for the design of bracket parts.
