摘　　要：某悬架三角臂由于在装车过程中与其它部件发生干涉,在形状上进行了改进。按照3D设计图,运用hypermesh软件对改进后的三角臂建立有限元模型,根据实车运行工况,对三角臂受力最恶劣的制动工况进行分析,从三角臂的形变与应力分布图,可知改进后的三角臂在解决干涉的基础上,强度和刚度均都有所提高,能够满足设计要求。The shape of the suspension control arm is ameliorated due to its interference with other parts in the using. According to 3D drawings of suspension control arm, finite element model is built using hypermesh software. According to the actual vehicle operating conditions, force analysis of the control arm under the braking condition is carried out. By analyzing strain and stress of the control arm, the strength and stiffness of the ameliorated control arm structure can meet the design requirements after solving the interference.
