基于PC-Crash的车辆侧翻事故再现仿真实验

Research on reappearance simulation experiments based on PC-Crash software rollover accident

PC-Crash再现交通事故是根据交通现场勘查结果及事故调查结果,构建交通事故现场场景并导入模型,设定模型的参数和初始运动状态,对交通事故发生过程进行模拟演示,将演示结果与实际交通事故进行比较,分析是否存在差异并判断存在差异的原因,进一步调整模型的参数和初始运动状态,直至演示结果与实际事故高度吻合。在分析引发车辆侧翻事故各种可能因素的基础上,着重介绍了PC-Crash软件仿真车辆侧翻事故的基本步骤。通过交通事故实例,演示了PC-Crash软件变量参数的设置和调整方法。

The PC-Crash reappearance accident is based on the field exploration and transportation accident investigation as a result,the construction of traffic accident scene into the model,and parameters and initial movement condition of the model,to simulate the process of traffic accident and demonstration, will demonstrate the results compared with the actual traffic accidents,analyze whether there is difference and determine the cause of the differences,so as to further adjust the model parameters and the initial motion,straight to demonstrate highly consistent results with the actual accident.On the analysis of the cause of vehicle rollover accidents,on the basis of various possible factors,this article introduces the PC-Crash software simulation rolled over the basic steps of traffic accidents.Taking the traffic accident as an example,this article demonstrates the PC-Crash software variable parameter setting and adjustment method.
