摘要： 基于 ABAQUS 软件对某车型控制臂球销座进行了拉脱力仿真分析，根据自适应接触理 论，采用显示动力学求解器，仿真验证出极限拉脱力为 53.1 kN 时峰值位移量为 8.77 mm，将 计算出的拉脱力-位移关系曲线与台架试验测试曲线进行拟合对标，误差率控制在 5%以内， 其结果满足一致性要求，归纳总结了针对性较强的，具有较高精度的仿真分析方法流程，为 相关零部件的设计开发及试验验证提供了理论指导。

Abstract: Based on ABAQUS software, the ball pin seat of the control arm which a certain vehicle was simulated with pull-out force. According to the adaptive contact theory, the display dynamics solver was used to simulation verifies that the peak displacement is 8.77 mm when the ultimate pull-out force is 53.1 kN, use which to compare the calculated pull-out force-displacement curve with the bench test curve, the error rate shall be controlled within 5%, and the results met the consistency requirements. The simulation process with stronger pertinence and high precision is summarized, which provides theoretical guidance for the design, testing and experiment verification of the relevant parts.
