将多体动力学方法与行人伤害分析相结合对一起真实的人车碰撞事故进行了准确的仿真再现,研究分析了碰撞过程中行人的动力学响应和伤害.事故再现结果与实际情况及法医尸检结论吻合,有效地验证了方法和模型的正确性.在此基础上计算得出行人头部及下肢伤害与汽车碰撞速度的变化关系,可为改善汽车的行人安全性提供参考.
Combining the multi-body dynamics method with the pedestrian injury analysis, a real simulation of the collision between the vehicle and the vehicle was carried out, and the dynamic response and injury of the pedestrian during the collision were analyzed and analyzed.The results of the accident reconstruction and the actual situation and the autopsy autopsy The results are in good agreement with each other and validate the correctness of the method and the model.On this basis, the relationship between pedestrian head and leg injuries and the collision speed of the car is calculated, which can provide reference for improving the pedestrian safety of the car.
