角度碰撞中车车碰撞兼容性的研究

摘要

For investigating the crash compatibility in vehicle to vehicle oblique crash, LS-DYNA is used to simulate and compare the dynamic response of vehicle between two conditions:with and without the participation of front rail in major deformation, and the effects of vehicle mass on crash response and crash compatibility in both conditions are analyzed. The results show that the effects of vehicle mass on crash compatibility with front rail partic-ipating in major deformation are more significant than that without.%为探究车与车角度碰撞下的车辆碰撞兼容性，运用LS-DYNA对比研究车与车角度碰撞中汽车前纵梁参与和不参与主要变形两种工况条件下的汽车动态响应，分析两种工况下整车质量参数对碰撞响应和碰撞兼容性的影响。结果表明，纵梁参与主要变形时，质量参数对两车碰撞兼容性的影响比纵梁未参与主要变形时更显著。
