摘　　要：根据后悬架硬点坐标,建立双横臂独立悬架仿真模型.利用多体动力学理论,在加速和车轮上跳工况下,对下控制臂进行载荷分析;在相应工况下,运用有限元理论,对下控制臂进行有限元分析.分析结果表明,下控制臂满足设计要求.The model of the rear double wishbone independent suspension was built according to hard point coordinates of the rear suspension. Then the model was separately simulated for the load analysis of lower control arm in the acceleration and vertical bounce with multi-body dynamics theory. The lower control arm was analyzed using finite element theory. The analysis result shows that, the lower control arm meets the design requirements.
