| 摘 要： | 为了探究车车斜角碰撞模式下的乘员损伤的特点,分别建立了某款小轿车与某款SUV在不同碰撞重叠率以及不同碰撞严重程度下的车车斜角碰撞有限元模型,并采用有限元软件和多刚体软件相结合的方法分析了车车斜角碰撞中不同碰撞重叠率和不同碰撞严重程度条件下的乘员损伤.结果显示,假人各部位中,头部和下肢损伤受碰撞严重程度和碰撞重叠率的影响较大,在多种重叠率工况中,30%重叠率工况下假人损伤受碰撞严重程度的影响比较敏感,70%重叠率工况下假人损伤较小.

Study on the Driver Injury in Vehicle to Vehicle Oblique Crashes |

| Abstract: | FE models of different oblique crash cases between passenger car and SUV in different crash overlaps and impact severities were developed to investigate the injury responses of the driver in oblique crashes. The method combining the FE and multi-body software was used to analyze the injury response of driver in different cases. It is shown that the impact severity and the crash overlap have great influence on the injury response of the head and the lower limb. It is also indicated that the driver injury response in 30% crash overlap case is more sensitive to the impact severity and the driver injury response in 70% crash overlap case is the lowest in three crash overlap cases. |
