为了较好地实现汽车的安全性,现代轿车的承载式车身一般都采用防碰撞的车身结构设计,这对车身维修提出了更高的要求。1轿车碰撞类型与车身的安全性车身碰撞的类型基本分为3种:正面碰撞、侧面碰撞和追尾碰撞。实验证明,在纵向碰撞(正面碰撞和追尾碰撞)事故中,前部和后部均为弹性结构而中部为刚性结构, In order to realize the safety of the car better, the load-bearing body of the modern car generally adopts the anti-collision body structure design, which sets higher requirements for the body maintenance. A car collision type and the body’s safety Car body collision types are basically divided into three kinds: frontal collision, side collision and rear-end collision. Experiments show that in the longitudinal collision (frontal collision and rear-end collision) accident, the front and rear are elastic structure and the middle is a rigid structure,
