摘　　要：车身B柱耐撞性决定整车的侧碰安全性,同时也要满足轻量化。基于现有架构平台,采用热成型结合TRB技术,应用2k因子实验设计结合CAE分析,对车身B柱进行优化设计,研究B柱在满足侧碰安全目标下如何实现轻量化设计。B post of body is a key component for vehicle safety performance, which generally decide the whole vehicle safety performance. As the ear criterions upgrading, and environmental pro- tection is the trend of the car industry developing, the more strict safety assessment criterion is put for- ward by professional authority in auto industry. This paper applied 2k factors experiment and CAE anal- ysis result to optimize design, how to realize the B post light weight under meeting impact performance is studied using hot forming and TRB technical, all.
