摘要： 为进行人车碰撞事故分析和汽车安全研究，建立了人体模型及人车碰撞事故的有限元方法仿真模型。在人体模型中，根据中国人体尺寸及惯性参数，基于男子第P50百分位人体参数，包含15个体段；车辆模型则简化成与人体接触的前端外形结构。通过与实际人车碰撞事故录像及以往的理论研究成果进行对比，对该模型进行微观验证和宏观验证，并在实际的事故案例分析中进行应用。该模型可以对实际的事故进行再现分析和车辆碰撞速度估算。

Abstract: A computer simulation model of pedestrian-vehicle accidents was developed to analyze pedestrian-vehicle accident and vehicle safety research. The model was based on finite element method (FEM) and human dimensions and inertial parameters of Chinese adult human body. Human Body Model was set up for the men's 50 percentile which including 15 individual segments, and the vehicle model was simplified into the front-end outline structure which contact with the human body. The microscopic validation and the macro validation of the simulation model were verified compared with a real video of pedestrian-vehicle accident and theoretical results. Thus, the simulation model can estimate the vehicle velocity in pedestrian-vehicle accident and can be applied to a real traffic accident reconstruction.

Key words: pedestrian-vehicle accident reconstruction, simulation of finite element method, pedestrian dummy, parameters of Chinese human body
