Abstract

With the development of transportation industry, there’re more and more traffic accidents caused by the vehicle driving, bring great potential safety hazard and economic risks to the drivers and their families. Therefore, it’s of great importance to take a study on airbag application especially on computer simulation of airbag unfolding. In this paper, the airbag made of Nylon 66 unfolding process and stress and strain distribution between human and the car during the frontal collision was finite analyzed. The results showed that, when the crash occurs human body moves forward because of inertia and touches or impacts the unfolded airbag. During that process most energy is absorbed, giving buffer to the violent collision between human body and airbag with a equivalent stress of 0.0043MP. The result provides a theoretical basis and reference to predicting the possibility of various situations during crash and improving airbag stability.
