Based on the research of Yangtifu and the like, namely 'optimization of car body in E-NCAP column collision requirement', the article shows that the car column collision performance is one of the important evaluation criteria of E-NCAP, the performance quality is usually judged through the injury index of a dummy, wherein the injury of the dummy is mainly determined by two aspects: (1) a dummy living space in and after the collision; (2) the impact transmitted by the automobile parts to the dummy in the collision is the secondary impact. Specifically, the narrower the living space of the dummy during and after the collision, the greater the impact that is transmitted to the dummy by the automobile parts during the collision, and the worse the automobile pillar impact performance. Based on the above background, how to improve the pillar impact performance of the automobile, reduce the intrusion speed of the components while widening the production space of the user is a key point in the design consideration of the automobile.
