摘　　要：采用FC-Crash对道路交通事故进行重构已是比较成熟的方法,从中可以获取事故车辆的三维加速度与角加速度波形,但无法模拟出乘员的伤情指标,而Madymo软件是建立包含车体、安全带、安全气囊、假人在内的约束系统模型,在给定的加速度下可以计算出人员的伤害指标。故将PC—Crash与Madymo进行耦合计算,即可获得事故车辆在事故过程中的运动参数,再现驾乘者的运动响应,进而得到人员的伤情指标。这一新的事故再现方法的研究结果表明:PC-Crash与Madymo的耦合计算可较为准确地再现事故车辆的减速和旋转运动状态,以及驾乘人员的响应运动状态,对结合致伤机理深入分析事故原因具有重要的意义,也可为交通事故鉴定提供新思路。Using PC-Crash to reconstruct road traffic accidents is a relatively mature method,from which the 3D acceleration and angular acceleration waveforms of the accident vehicle can be obtained,but the injury indicators of occupants can't be simulated.A restraint system model consisting of vehicle body,seat belts,airbags and dummies constructed by Madymo software can calculate the injury indicators of occupants at a given acceleration.Therefore,by coupling calculations of PC?Crash and Madymo,the motion parameters of accident vehicle during the accident can be obtained,the motion response of the driver and passengers can be reconstructed,thus the injury indicators of occupants can be obtained.The research results of this new accident reconstruction methods showed that the coupled calculation of PC?Crash and Madymo could accurately reconstruct the deceleration and rotation motion states of the accident vehicle as well as the response motion states of the driver and passengers,which have great significance in in-depth accident causes analysis combining the occupant injury mechanism,and can provide new insights for traffic accident identification.
