摘要/Abstract

摘要： 为提高正面40%偏置碰撞中女性驾驶员安全性,利用仿真软件MADYMO建立包括驾驶员座椅、转向系统、安全气囊、男性假人、安全带等在内的男性驾驶员约束系统模型,并经试验验证;然后参照2015版欧洲新车评价规程,调整驾驶员座椅位置,并用女性假人代替男性假人,建立女性驾驶员约束系统模型;最后利用女性驾驶员约束系统模型,分析驾驶员约束系统参数对女性驾驶员伤害的影响。结果显示,缩短转向柱长度,将使头部与胸部伤害降低,但使颈部伸张弯矩增加;当气囊4点钟、8点钟、12点钟拉带长度分别为180,180,270 mm时,头部伤害指标较原始值上升25.50%;当安全带限力等级由5.0 kN降至2.5 kN时,胸部压缩量降低14.44%。

Abstract: In order to improve female driver safety in frontal 40% offset collision, firstly, a male driver restraint system model including driver seat, steering system, safety airbag, male dummy, safety belt and so on was established by simulation software MADYMO, and the model was verified by test, secondly, according to 2015 European New Car Assessment Programme, a female driver restraint system model was established by adjusting driver seat position and substituting female dummy for male dummy, finally, influences of the parameters of driver restraint system on injury to female driver were analyzed by means of the above female driver restraint system model. The results indicate that, as the steering column length decreases, the head and chest injury decrease, but the stretch bending moment of occipital bone increases,that as the length of the airbag strap at four o'clock, eight o'clock, twelve o'clock position is 180 mm, 180 mm, 270 mm respectively, the head injury criterion rises by 25.50% compared with the original value,and that as the limited load level of safety belt declines from 5.0 kN to 2.5 kN, the chest compression displacement falls by 14.44%.
