摘　　要：本文选取最新的一个真实事故案例进行了建模和仿真,分别从车辆和行人的身高、体重还有碰撞速度三个方面角度来分析其对行人抛距的影响,将仿真结果中导出的数据参量与实际发生事故的数据进行了对比,通过分析验证了仿真模型的精度和仿真再现的可行性。根据所验证的事故建模和再现方法,对NAIS数据库里的10起案例进行再现从而得出行人抛距、头部碰撞参数和行人损伤评价指标的拟合曲线和回归方程,指出在我国交通事故中,头部损害造成行人死亡的主要原因。以此为交通管理部门能够准确、客观地处理道路交通事故提供了良好的方法,供交通事故管理部门对事故发生的全过程进行了解和分析。This paper selects the latest real accident case for modeling and simulation, analyzes the impact of vehicles and pedestrians on the throwing distance of pedestrians from the perspectives of height, weight and collision speed, compares the data parameters exported from the simulation results with the actual accident data, and verifies the accuracy of the simulation model and the feasibility of simulation reproduction through analysis. According to the verified accident modeling and reproduction methods, 10 cases in the NAIS database were reproduced to obtain the fitting curve and regression equation of pedestrian throwing distance, head collision parameters and pedestrian damage evaluation index, pointing out that in traffic accidents in China, the main cause of pedestrian death caused by head injury was obtained. This provides a good method for traffic management departments to accurately and objectively deal with road traffic accidents, and provides traffic accident management departments to understand and analyze the whole process of accidents.
