【摘要】 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.更多还原

【Abstract】 This paper combined multi-body dynamics method with pedestrian injury analysis to reconstruct a real car-pedestrian collision accident exactly and analyzed the dynamic response and injuries of pedestrian in the course of collision.The reconstructed results are in accord with the actual accident situation and the (forensic) medical identification of pedestrian body,effectively prove the accurateness of the simulation methods and models.Based on those results,the relationship between pedestrian’s head and leg injuries and car impact velocity was studied which can provide references for improving cars’ pedestrian safety.更多还原
