Abstract

Abstract:

In order to meet the requirements of environmental protection and lightweight in China's automobile manufacturing industry, this study redesigns the B-pillar, the key component of automobile, based on hot pressing process. Then, The computer is used to validate the model of parts and components. In the process of modeling, the model of automobile parts under this process is established based on the finite element theory. At last, the vehicle crash experiment is designed according to the C-NCAP crash standard of our country. The simulation results showed that the quality of parts designed by this method can be reduced by 50% when compared with the traditional parts formed by cold pressing. At the same time, the passive safety of automobiles can be improved to a certain extent.

Key words: hot pressing, finite element, side impact, automobile lightening
