摘　　要：对某电动汽车麦弗逊悬架下摆臂进行有限元分析。首先对悬架进行运动学分析,得出作用在下摆臂各点的载荷;其次对同等厚度的下摆臂分别赋予钢材料和铝材料,采用惯性释放的方法分别对其进行静力学分析;最后以下摆臂最大变形量为约束条件对采用铝材料的下摆臂进行尺寸优化。结果表明:采用铝材料的下摆臂可以在保证静、动态性能的前提下有效降低自身重量。This article used FEM to analysis lower control arm of electric vehicle’s McPherson suspension.First,with the method of kinematic analysis,load obtained loads on the lower control arm.Followed by respectively assigned to lower control arm of the same thickness of steel material and aluminum material,and analysis it with the method of inertia relief.Finally,we use the largest deformation as constraints of size optimization on the lower control arm made of aluminum materials.The results showed that lower control arm made of aluminum materials can effectively reduce their weight to ensure that the premise of static and dynamic performance.
