摘要
以一起真实的车人碰撞事故为案例,利用PC-Crash软件,根据事故现场采集到的车人信息,建立车人碰撞事故现场模型;利用正交试验法对各参数的权重进行分析,由分析结果辅助车人碰撞事故的再现仿真;仿真得到的车人位置值、行人头部和胸部的动力学响应等与实际的车人位置测量值、行人的头部和胸部损伤程度相吻合,表明正交试验能有效地辅助PC-Crash进行事故仿真分析时的参数选取,得到合理的仿真结果。
A real vehicle-pedestrian crash case study was performed to establish the field model for vehicle-pedestrian crash acci- dent by PC-Crash, according to the relevant irfformation collected from the accident site. Then the olthogonal test was utilized to analyze the weights of various parameters and simulate the reconstruction of the vehicle-pedestrian crash in the assistance of analy- sis results. Vehicle-pedestrian position value and dynamic response on pedestrian＇ s head and chest were consistent with the meas- ured vehicle-pedestrian position value and the pedestrian＇ s head and chest dmnage. It indicates that the orthogonal test is able to effectively assist PC-Crash to select parameters in the accident simulation to obtain the reasonable results.
