某车型正面18°斜角碰撞试验中前排乘员损伤分析

Analysis of Front Row Occupant Injury based on 18°Oblique Frontal Collision Test

道路交通事故中车辆的碰撞方向通常呈一定角度。本文以某车型18°斜角滑台碰撞试验为例,分析了前排不同体位乘员各部位的损伤。结果显示:除大腿力外,50th假人其它部位的损伤指标均高于95th假人和5th假人,即前排乘员在相同斜角度碰撞工况条件下,中等身材乘员的上半身损伤较为严重,且95th假人各部位损伤指标曲线均迟于50th假人和5th假人;95th假人的大腿力损伤值高于50th假人和5th假人,即在相同斜角度碰撞工况条件下,较大身材乘员的下半身损伤风险较大。

The collision direction of vehicles in road traffic accidents is usually at a certain angle.Taking 18°angle sled collision test of a car as an example,the injury of the frontal occupants withdifferent percentile wasanalyzed in this paper.Test results show that the damage indexes of the 50 th dummy are higher than those of the 95 th dummy and the 5 th dummyexcept the thigh force,that is to say,the upper body injury of the middle-sized occupant is more seriousunder the same oblique collision condition,and the damage index curves of all parts of the 95 th dummy are later than those of the 50 th dummy and the 5 th dummy;The thigh force damage value of 95 th dummy is higher than that of 50 th dummy and 5 th dummy,that is to say,the lower body injury risk of larger occupant is higherunder the same oblique angle collision condition.
