摘　　要：基于车辆正面碰撞加速度波形简化的等效二阶梯形波,本文选取获得NHTSA五星评价的20款SUV车型,通过等效二阶梯形波关键参数与实车碰撞加速度波形、车体最大位移及WIC的相关性分析,探讨了等效二阶梯形波特征参数和乘员损伤的关系,为SUV车型的碰撞动态响应开发工作提供工程指导意义。Based on the simplifi ed equivalent second-order trapezoidal wave of the vehicle frontal collision acceleration waveform,this paper selected 20 SUV models that have obtained the NHTSA five-star rating.By analyzing the correlation between the key parameters of the equivalent second-order trapezoidal wave and the real vehicle collision acceleration waveform,the maximum displacement of the vehicle body and the WIC,the relationship between the characteristic parameters of the equivalent second-order trapezoidal wave and the occupant injury was explored.It provides engineering guidance for the development of collision dynamic response for SUV models.
