摘要

文章基于某款新能源车型按欧盟新车评价规程(Euro NCAP)进行的整车安全性能开发,对侧柱碰工况的胸压问题进行的性能研究,通过胸压问题的理论研究得出影响因子,并采用有限元仿真分析、滑台试验和整车碰撞验证结合的研究方式,提出车身结构、气囊包型、座椅发泡设计等的优化方案,最终提升了整车碰撞安全性能.研究表明,乘员的安全空间、气囊对假人安全约束、座椅状态的稳定性等都对胸压性能产生影响,据此提出的方案最后通过实车碰撞试验验证了优化方案的可行性.

Abstract

This article is based on the overall safety development of a new energy vehicle model Euro new car assessment program(NCAP),to conduct the performance study on the chest deflection problem on the side pole test condition.Through the theoretical research on the chest deflection problem and obtain the relative influence factors.And by using the research method of finite element simulation analysis,sled test and vehicle barrier test verification.The optimization of BIW structure,airbag layout,seat foam design is proposed,which finally improved the vehicle crash performance.This article shows that the safety space of occupant,the safety restraint on the dummy,the stability of the seat state,etc.,all have an important impact on the chest deflection performance,and the proposed solution is verified by the vehicle test and to be believed that is feasible.
