基于Pc crash的交通事故再现误差分析

Error Analysis of Traffic Accident Reconstruction Based on Pc crash

摘要:

对交通事故再现软件Pccrash中的特征参数进行分析，设计具普遍意义的车车斜撞模型，运用分析法、控制变量法先提取较主要的参数；再设定正交试验将这些较重要参数按权重大小排序.基于对特征参数的研究，探求这些重要参数对模拟结果影响的权重及产生影响的类型，以此寻求减小事故再现误差的方法，并用国内一起典型的车两轮车交通事故验证结论的正确性，为提高Pccrasch软件再现国内事故精度的研究建立基础.

Abstract:

The parameters in the Software Pccrash were analyzed in this paper. The work included: a carcar oblique impact model was designed, analysis and control variate method was used to acquire the key parameters and an orthogonal test was set to acquire the weights of these key parameters. Based on the parameters research the weights of the key parameters which influence the simulation result and the type of influence were obtained and used to seek the method for reducing traffic accident reconstruction Error.In addition,a typical traffic accident of fourwheel vehicletwowheel vehicle in China was reconstructed and confirmed the conclusion. The paper contributes to the further deep analysis about improving precision of traffic accident reconstruction in China with Pccrash.
