基于2021版C-NCAP和IIHS侧面碰撞工况车辆结构性能研究

Research on Vehicle Structural Performance based on 2021 Version of C-NCAP and IIHS in Side Impact Conditions

本文对2021版C-NCAP和IIHS侧面碰撞工况进行了详细的对比,并采用有限元分析方法对某款SUV车型的侧面碰撞结构性能进行详细分析。结果表明,IIHS侧面碰撞工况对车身结构耐撞性的要求要明显高于C-NCAP工况,相对应的B柱、前后车门的侵入量和侵入速度都有不同幅度的增加。

This paper makes a detailed comparison between the 2021 version of C-NCAP and IIHS side impact conditions,and uses the finite element analysis method to analyze the side impact structure performance of a certain SUV model in detail.The results show that the IIHS side impact condition has significantly higher requirements on the crashworthiness of the body structure than the C-NCAP condition.And the corresponding B-pillar,front and rear doors intrusion amount and intrusion speed all increase in different ranges.
