摘要
本文通过MADYMO软件对典型的车辆与行人侧面碰撞事故进行了模拟,输出最后一节颈椎(C7)的位移,加载到经过验证的某一基于人体解剖学结构的头颈部有限元模型中。通过仿真分析,得到头颈部的加速度、角速度等随时间的变化曲线和载荷力、HIC值等,并与多刚体模型的响应进行了对比。结果显示两种模型都可以有效预测行人在事故中的损伤风险,但有限元模型可以得到更多的损伤参数,相对而言可以更加准确地反映人体头颈部损伤响应。
A typical pedestrian-vehicle collision was simulated by MADYMO software.We get the displacement of the C7 cervical vertebra and load the displacement to a validated finite element model based on the human anatomic structure.The finite element model was calculated and gained the head acceleration,angular velocity,force and HIC.The injury parameters from finite element model were compare with the parameters from multi-body model.The result indicate both models can effectively predict the pedestrian injury risk,but the finite element model can gain more injury parameters and show the injury responses of human head-neck.more accurately.
