摘要: 为提高轿车正面碰撞中约束系统对不同体型女性驾驶人的保护效果,依据美国国家高速公路交通安全管理局(NHTSA)的一例实车碰撞试验数据,基于Madymo软件建立有效的驾驶侧仿真模型。利用人体放缩法建立符合中国成年女性身体尺寸的第5、50和95百分位的女性驾驶人模型,以正交试验法进行仿真试验,研究转向管柱倾角、座椅高度、安全带上挂点高度、座椅靠背倾角以及气囊点爆时间等参数的匹配对女性驾驶人损伤的影响。结果表明:女性驾驶人体型越高大,其整体损伤(WIC)值越低;约束系统模型优化后,能明显降低小身材和中等身材女性驾驶人WIC值。

Abstract: For the sake of improving the protection effect of the restraint system in a frontal collision of cars on different body shape female drivers, an effective model was established by Madymo according to data obtained from a real vehicle crash test by National Highway Traffic Safety Administration. A female model of the 5th, 50th, and 95th percentiles' body size of Chinese adult females was established. Then the orthogonal test method was used for the simulation test to study the match of steering column inclination, height of the chair and seatbelt, angle of the backrest to chair and the time of the airbag's point-burst that have impact on female drivers. The results show that the higher and larger the female body type is, the lower the WIC will be, and that the optimized restraint system model can significantly reduce the WIC value of female drivers with small or medium size.

Key words: constraint system, female drivers, weighted injury criterion (WIC), body type, Madymo, orthogonal test
