Study on the Automotive Body Collision Damage and the Repair Method

In order to improve the repair quality and efficiency of automotive body collision 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 structural damage of integral body, the paper makes body damage repair process, analyzes the main factors which affect the body fixed and measurement, and puts forward a method which uses a multi-point pulling and the computer 3D measurement system to repair the damage. Finally, the validity of the method is verified by the collision case. The results show that the method can effectively control the position deviation of the body structure not more than 3mm, it can also improve the repair quality of automotive collision and reduce reworking rates effectively.
