Parameter Weight Analysis of Car Side Impact Accident Reconstruction

摘要

In order to improve the accuracy of car side collision accident reconstruction, a domestic accident case is taken as an example to reconstruct the accident through PC-CRASH and design the orthogonal experiment. Through experiments, the weight ranking of PC-CRASH side impact reconstruction is obtained. According to the weight of the parameters, the accident case is reconstructed again. The results show that th e error between the reconstructed result and the actual accident result after the targeted adjustment of the parameter is significantly smaller than the error between the reconstruction result obtained from the unadjusted adjustment parameter and the actual accident result. Therefore, it is verified that the accident reconstruction according to the weighting of the affected parameters can improve the accuracy of the result of PC-CRASH accident reconstruction of the side collision of the car.
