The Research of a New Energy Car Structure on the Frontal Crashing

Chang-yong DENG, Chao-qun HUANG, Xian-kun WEI, Tie TIAN


Taking a sedan as the research object, the frontal impact simulation was done. The results showed that the corresponding results of the structure deformation of the body are in agreement with the experimental data. On account of the driving zone and driver survival space that were compressed seriously, some improvements of the front carling were taken in designing. The structural simulation analysis and dummy injury analysis were done to verify the effectiveness of the improved scheme. Pillar B improved significantly reduce the peak acceleration, and dummy injury were significantly reduced, greatly improving the car's passive safety.
