摘　　要：为提高汽车车身碰撞损伤的维修质量和效率,确保汽车修复后的安全性、平顺性和可靠性,在分析汽车碰撞受力的基础上,探讨承载式车身变形特性。针对承载式车身结构性破坏,制定损伤修理流程,分析影响车身固定和测量的主要因素,提出用多点复合拉伸、辅助计算机测量的方法来修复损伤,最后通过车辆前端碰撞修复案例验证了方法的有效性。结果表明:该方法能有效控制车身构件的位置偏差不超过±3mm,提高碰撞汽车的修复质量。In order to improve the repair quality and efficiency of automotive bodycollision damage and ensure the safety and reliability of the automobile after repairing,the paper discusses the integral body deformation characteristics based on the analysis of automobile impact force.Aiming at the structural damage of integral body,the paper makes body damage repair process,analyzes the main factors which affect the body fixation and measurement,puts forward a method which uses a multi-point pulling and the computer 3D measurement system to repair the damage,and verifies the validity of the method by the collision case.The results show that the method can effectively control the position deviation of the body structure not more than 3mm,and can also improve the repair quality of automotive collision and reduce reworking rates effectively.
