摘要

面向受害人体型特征的交通事故再现依据事故遗留下的制动印迹、车身变形、人体损伤等信息,建立汽车及符合受害人体型特征的人体模型,利用数值仿真技术获得碰撞前车辆速度及车人接触位置,结合多刚体动力学和人体损伤分析等理论,得出车辆变形及人体损伤部位的生物力学数值。通过上述方法对一起车人碰撞事故案例进行实际应用,并比较行人不同体型特征对事故仿真结果的影响,分析结果表明:与采用标准百分位假人仿真结果相比,计算结果能够更好的与现场勘测及法医鉴定相吻合,从而为交通事故责任认证提供科学的理论依据和数值参考。




Abstract

Traffic accident reconstruction face the body characteristic of victim according as the accident imprint left by the brakes, automobile body and other objects deformation, human body injury and other information, it establishes the automobile and human body model conform to the characteristics of victims. The numerical simulation technique is used to acquire vehicle speed before collision and location of vehicle-pedestrian contact. With multi-body dynamics and human injury analysis theory, obtains the vehicles distortion and the human body damage spot biological mechanics value. Carries on the practical application to the vehicle-pedestrian collision accident case, the method introduces in detail the model building, the collision contact the definition and the value simulation process, the value simulation result which and the scene survey and medical examiner the computation obtains appraise the result to tally, thus provides the theory basis and the value reference for the traffic accident responsibility authentication.
