摘要
为研究汽车与摩托车碰撞事故中不同因素对骑车人损伤的影响,基于国家车辆事故深度调查体系(NAIS)中的一个真实案例,运用PC-Crash软件建立汽车前部与摩托车右侧的碰撞模型;在此模型基础上,从汽车、摩托车、摩托车骑车人等3个方面考虑影响因素并设计正交试验,分析其权重大小,并探讨显著性因素对骑车人损伤的影响过程。研究表明:汽车车速、骑车人坐高、发动机罩前端缘离地高度等是显著影响损伤的因素;骑车人坐高越低,骑车人与汽车发生碰撞时间缩短,碰撞后造成骑车人的损伤越重;汽车发动机罩前端缘离地高度越大,碰撞后造成骑车人的损伤越轻。
In order to study the impacts of different factors on injury to the rider in a collision accident between automobile-motorcycle,based on a real case in the National Vehicle Accident Investigation System (NAIS),a model was built for collision between the front of the car and the right side of the motorcycle by using the PC-Crash software.Based on this basis,the influencing factors were identified and orthogonal experiments involving the car,the motorcycle,and the motorcycle rider were designed and carried out.The weights of them were analyzed.The influences of significant factors on the process were explored.Research shows that the car speed,rider's sitting high and hood front edge height from the ground are significant factors,that the smaller the rider's sitting high,the shorter the moment for the rider collision with the automobile,the injury to the rider,and that the greater hood front edge height from the ground,the smaller the injury to the rider.
