车车事故再现方法研究

Car accident reappearance method research

为研究车车碰撞过程中,事故各参数对再现车速的影响,根据国家车辆事故深度调查体系(NAIS)中的一个真实案例,利用基于能量模型的定值分析法及不确定度分析法进行数据计算分析,在此基础上利用Pc-Crash仿真软件进行事故再现。以车辆实际损坏信息、最终相对位置等信息为评价标准,比较定值分析法及不确定度分析法,并分析事故参数不确定因子对车速影响。

For the study of car collision process, the influence of parameter to represent the speed of accident, according to a real traffic accident case in the national vehicle accident in-depth survey system (NAIS), to make data analysis based on the energy model of fixed value analysis and uncertainty analysis, then to make the accident reconstruction using the simulation software PC-Crash. In actual damage information of the vehicle and finally the relative position as evaluation standard, to compare fixed value analysis with uncertainty analysis, and to analyze the uncertain parameter factors influence on the speed of the car in accident.
