汽车小偏置碰撞侵入量与车身结构的分析

Analysis of Intrusion Amount of Small Off set Car and Body Structure

近年来,25%正面小重叠碰撞试验在汽车被动安全领域内,受到了越来越多的关注。在中国,C-IASI(中国保险汽车安全指数)也开始进行了正面小重叠碰撞试验的测试与评价。本文对车辆进行25%正面小重叠碰撞试验的结构侵入量进行了数据分析,研究在碰撞过程影响车身结构侵入量的原因,以及指出车身结构在未来研发中的趋势。

In recent years,the 25%frontal small overlap crash test has received more and more attention in the fi eld of automobile passive safety.In China,the C-IASI(China Insurance Automotive Safety Index)has also begun to test and evaluate the frontal small overlap crash test.This paper analyzes the structure intrusion amount of the vehicle in the 25%frontal small overlap collision test,studies the reasons that aff ect the intrusion amount of the body structure during the collision process,and points out the trend of the body structure in the future research and development.
