摘　　要：侧面碰撞在实际交通事故中占有很大的比例,因此,研究侧面碰撞对于保护乘员安全是很重要的。改善车辆结构以减少乘员伤害情况的方法有许多,其中改善B柱的结构对侧面碰撞的影响很大。而通过对两辆车B柱更改前后侧面碰撞乘员伤害情况的研究,提出"合理的B柱结构可以降低乘员伤害指标"的结论,可以使车辆在不安装气囊的情况下,降低对车内乘员的伤害程度。Side collision takes a big proportion of the actual traffic accidents, so it is important to research side collision for the protection of passengers. There are some kinds of methods about improving the structure of vehicle in order to reduce the injury of passenger, one of them is to improve the structure of B pole which has a remarkable influence on side collision. Through the research of the passenger injury in the side collision before and after the improvement of the B pole, a conclusion is obtained that the structure of B pole can reduce the injury index of passenger, and it is possible that the passenger injury index can be reduced even if there is no gas bag in vehicle.
