摘　　要：整车安全性能应同时满足NCAP体系的要求和中低速碰撞的乘员保护要求。本文中从车体碰撞强度和乘员伤害的角度出发,利用MADYMO软件优化气囊点火时刻,为气囊标定提供参考;同时总结了低速碰撞的乘员伤害评价限值,使乘员在不同的碰撞工况下都能得到最佳保护。The vehicle safety performance should meet both the NCAP system requirements and the occupant protection requirements in medium and low speed impacts.In this paper,starting from the angles of vehicle body crashworthiness and occupant injury,the ignition timing of airbag is optimized by using software MADYMO,providing references for airbag calibration.In addition,the limits of occupant injury evaluation in low-speed impacts are summarized,assuring the best occupant protection in different crash conditions.
