摘要： 通过对标准多刚体假人和有限元人体模型进行拆分、组合、缩放，建立基于受害人真实体型特征参数的多刚体-有限元组合式假人模型，应用于一起真实两轮电动车交通事故的模拟.采用摄影测量法计算车辆碰撞速度，对事故发生时刻的现场进行三维重构，分析了碰撞后人和车的动力学响应以及电动车骑车人的损伤情况.碰撞后人和车的运动形态与真实情况基本吻合，通过模拟计算得到假人头部损伤准则(HIC)值、小腿最大弯矩和颅骨von Mises应力云图，人体损伤判定和法医鉴定结果一致，有效验证了组合式假人模型用于交通事故模拟的正确性和准确性.

Abstract: By combining the standard multi-rigid body dummy model and the finite element human model, the multi-rigid-finite element combined dummy model was established based on the real body characteristic parameters of the victim, and it was applied to a real two-wheel electric vehicle traffic accident. Using the photogrammetric method to reconstruct the scene, we studied the dynamic response of the vehicle after the collision and the damage of the electric vehicle cyclist. The movement of persons and cars after collision is basically consistent with the real situation. The head injury criterion (HIC) value of the dummy, the maximum bending moment of the calf and the von Mises of the skull were obtained through the simulation. The results show that human injury in the simulation are consistent with those of forensic identification. Our study effectively validates the correctness and accuracy of the combined dummy model in accident simulation.
