| 摘 要： | 为了研究小空间车型第2排乘员在正面碰撞过程中受到的伤害,利用仿真分析的手段,对比分析了不同的车体碰撞波形、乘员布置空间以及约束系统性能参数对第2排乘员伤害的影响,确定了安全带限力等级、车体碰撞波形及第2排座椅坐垫的布置角度是影响第2排乘员保护安全性能的关键因素.针对第2排乘员布置空间较小的车型,在保证第2排假人头部伤害满足目标要求的情况下,减小安全带的限力等级,增大第2排假人头颈部及胸部的前移量,以降低假人颈部及胸部的伤害,从而有效改善了第2排乘员的伤害情况.

Optimizing the Performance of 2nd Row Occupant Protection for Small Cars |

| Abstract: | The purpose of this paper is to reduce injury to rear seat passengers in frontal crash. The influencing factors of 2nd row dummy injury value on various body impact pulse, the occupant layout and restrain constrain system performance are analyzed. The key factors for influencing occupant safety protection are confirmed, including seatbeh force limit grade, automotive body impact pulse and seat-pan angle. Focus on car model which has narrow space in 2nd row seat, when the head injury value of 2nd row dummy meets the target requirements, decreasing the seatbeh force limit grade and enlarging the motion displacement of the dummy head and chest to reduce the injury is illustrated in this paper. |
