摘要/Abstract

摘要： 为降低后排左侧乘员在轿车60°斜角碰撞刚性壁障时的损伤程度,利用Presys建立有限元轿车、刚性障碍壁和假人整体模型,经Ls-Dyna求解计算后用Presys有限元软件分析30、40、50 km/h车速下的后排左侧乘员损伤情况。结果表明:随着碰撞车速的增高后排左侧假人头部加速度和颈部受力增大;碰撞车速为40 km/h时假人头部Y轴加速度比其他2种碰撞车速大;假人胸部加速度及加速度增幅随着碰撞车速的增加而增大。

关键词: 斜角碰撞, 后排乘员损伤, 碰撞车速, 仿真, Presys有限元软件

Abstract: In order to study the characteristics of the rear left passenger injury in car impacting a rigid barrier wall at 60° oblique angle, a finite element model was built for the car, the rigid barrier wall and the dummy by Presys. After calculating by Ls-Dyna, Presys finite element software was used to analyze the left rear occupant damage at 30, 40 and 50 km/h. The results show that with the increase of impact speed,the acceleration on the head and the force on the neck increase, that when the impact speed is 40 per hour, the dummy head Y-acceleration is the highest, and that there is a positive correlation between both the chest acceleration and the amplification of the acceleration increase and the impact speed.

Key words: vehicle oblique crashes, injury response of rear left side passenger, impact velocity, simulation, Presys finite element software
