40%重叠可变形壁障碰撞和侧面碰撞试验探究

Research on 40%Overlap Deformable Barrier Collision and Side Impact Test

针对在汽车安全交通事故中致伤率和致死率较高的两种碰撞形式,主要研究40%重叠可变形壁障正面碰撞和侧面碰撞,并按照中国新车评价规程2015版进行整车试验,通过试验后车身变形量和假人伤害值进行分析,得出两种类型碰撞对应车身结构损坏和乘员重点损伤部位,为后续新型车辆被动安全保护改进提供参考。

In view of the two types of collisions with high injury rate and fatality rate in vehicle safety traffic accidents,this paper mainly studies 40%overlap deformable barrier collisions and side collisions.According to the Chinese New Car Assessment Program 2015,vehicle test is carried out.Body deformation and dummy injury value are analyzed.It is concluded that the two types of collision correspond to structural damage of the vehicle body and the key damage parts of the occupant,which is a reference for passive safety protection of subsequent new vehicle.
