摘　　要：汽车-行人交通事故中行人损伤的重建分析在事故处理与成因鉴定中起着重要作用。为探讨碰撞中的不同成伤条件对行人下肢损伤程度的影响机制,利用THUMS人体有限元模型及LS-Dyna仿真软件构建人车碰撞仿真平台。研究表明:利用有限元仿真可以模拟人车碰撞事故中不同成伤参数下行人下肢的动力学响应并进行损伤评定。该方法有利于分析研究交通事故下行人下肢损伤的成因机制,同时能对事故的司法鉴定提供科学依据。Reconstruction analysis of pedestrian injury in vehicle-pedestrian traffic accident plays an important role in accident treatment and cause identification.In order to explore the influence mechanism of different injury conditions on the degree of lower limb injury of pedestrians in the collision,the THUMS human finite element model and LS-Dyna simulation software were used to construct a human-vehicle collision simulation platform.The results show that the finite element simulation can simulate the dynamic response of pedestrian's lower limbs under different injury parameters in human-vehicle collision and evaluate the damage.This method is helpful to analyze and study the cause mechanism of lower limb injury of pedestrians in traffic accidents,and has important guiding significance for the judicial expertise of accidents.
