- Lightweight is a major issue facing the automobile industry today. How to achieve lightweight while ensuring crash performance is a common problem and challenge facing all major OAs. In order to achieve the goal of lightweight body while ensuring collision performance, this paper based on a certain high-end new energy vehicle, through the application of variable-thickness rolled blank (VRB) technology in B-pillar instead of the original B-pillar reinforced plate welding scheme, combined with collision simulation analysis technology, finally achieve the lightweight effect of 10% weight reduction while meeting the collision performance of this high-end new energy vehicle. The application of the scheme has a certain reference function for the industry.
摘要： 轻量化是当今汽车工业面临的一大课题，如何在实现轻量化的同时又能保证碰撞性能 是各大主机厂共同面临的问题和挑战。为了实现车身轻量化的同时又能保证碰撞性能这一目 标，文章基于某款中高端新能源车型，通过在 B 柱应用变厚度轧制板（VRB）技术代替原始 的 B 柱加强板拼焊方案，同时结合碰撞仿真分析技术，最终实现该款中高端新能源车型在满 足碰撞性能的同时，降重 10%的轻量化效果，方案应用对于行业有一定借鉴和参考作用。
