摘要
乘员下潜是碰撞事故中的一种非常危险的现象,可能导致乘员的严重伤害。鉴于目前尚无判断下潜倾向的准则,本文中提出腰带在骨盆上的相对位置LBOP和髂骨所受力矩与力的比值IMFR两个准则,并利用混III5百分位女性假人的有限元模型对所提出的准则进行了仿真试验验证。最后,通过应用该准则,评估了安全带腰带水平角度对乘员下潜倾向的影响。
Submarining is a very dangerous phenomenon in crash accident and may lead to severe injury of occupant. In view of the lack of criteria for the judgment of submarining tendency so far, two criteria are put forward in this paper, i. e. the criterion of lap belt position on pelvis （ LBOP） and the criterion of iliac wing moment to force ratio （IMTR）, which are then verified by simulation test on a FE model for Hybrid-III 5th percentile female dummy. Finally the effects of lap belt angle on the submarining tendency of occupant are evaluated by applying proposed criteria.
