轿车完全重叠追尾货车碰撞相容性研究

Research on Vehicle Collision Compatibility of Fully Overlapped Rear End Collision

在交通事故中,追尾事故占了很大比例,尤其是物流业高速发展的今天,轿车追尾货车的事故逐渐增多。这类事故轿车乘员有较高的死亡率,主要是由于车辆之间不同的碰撞相容性造成的。基于碰撞相容性因素,提出将轿车前壁挡板侵入量作为衡量指标之一,应用Hypermesh仿真模拟软件做前处理、LS-DYNA求解器求解计算结果、Hyper View做后处理和数据分析,探讨了碰撞相容性在完全重叠追尾碰撞中所起的重要作用。

In the traffic accidents, the rear-end collision accounts for a large ratio, especially in the rapid development of the logistics industry. There is a higher mortality rate for car occupants in this kind of accident, due to the different collision compatibility between vehicles. Based on collision compatibility factors, front wall baffle intrusion was considered as one of the measurement index. The simulation software I-Iypermesh was used to make pretreatment, the solver LS-DYNA was used to solve and calculate results, HyperView was used to make post-process and data analysis, the important role of collision compatibility in fully overlapped rear-end collision was discussed.
