Study on evaluation indexes of the full width deformable barrier test

Abstract

In order to evaluate the crash compatibility of vehicles, the full width deformable barrier is introduced into the vehicle crash test. Real car to car frontal collision is better simulated by installing deformable barrier on the load-cell wall . By the load-cell wall data, the values and distribution of vehicle frontal collision loads can be further obtained. Based on this, the full width deformable barrier tests are conducted for different structural sedans and SUV. The height index, homology index, horizontal structure interaction index(HSI), vertical structure interaction index(VSI), and minimum load-cell index are analyzed and compared. The results indicate that there is uncertainty when calculating the homology index RH and the evaluation indexes proposed by FIMCAR repeat the first step of VSI and HSI. Therefore, the height index, VSI, and HSI indexes are selected as effective indexes for evaluating the compatibility of the full width deformable barrier test.
