基于侧面碰撞的远端乘员头部伤害及轨迹分析

Analysis of Head Injury and Trajectory of Far Side Occupant Based on Side Impact

为了探索Euro-NCAP Far Side试验中远端乘员头部伤害的产生原因及运动轨迹,基于某款车型的试验数据,初步提出了产生此现象的原因,运用TEMA软件对试验数据进行深入分析研究。结论表明:在侧面碰撞远端乘员保护中,头部主要伤害为RY的剪切力及张力,其次是Z方向的头部的拉应力及压应力。其中RY方向的剪切力及张力远远高于他方向的剪切力及张力。

In order to explore the cause of the head injury and trajectory of far side occupant in Euro-NCAP Far Side Test,based on the test data of a certain vehicle model,the reasons for this phenomenon were preliminarily proposed,and the test data were analyzed and studied using TEMA software.The conclusion shows that in the side impact of far side occupant protection,the main injury to the head is the shear force and tension in the RY direction,followed by the tensile stress and compressive stress of the head in the Z direction.The shearing force and tension in the RY direction are much higher than those in other directions.
