摘　　要：通过研究各类汽车车身B柱的结构特点及成形性能,对其进行全流程冲压工艺分析与设计。系统地研究了冲压方向、工艺补充面、板料尺寸、成形工艺参数对成形性能的影响。针对B柱拼焊板的冲压成形,研究了变间隙压边圈对焊缝偏移及成形性能的影响。基于知识工程(KBE)的理念,运用MicrosoftVisual C++6.0和UG/Open API软件开发了车身零件冲压分析系统及B柱冲压工艺设计界面。利用B柱冲压工艺设计界面对某车型B柱成形进行了工艺设计及仿真。结果表明:该工艺设计系统能很方便地指导B柱冲压工艺设计,仿真结果满足零件质量要求,提高了B柱零件工艺设计的速度。By studying the structure characteristics and forming performance of various automobile body B-pillars, the analysis and design of whole flow path stamping process were carried out. The effects of stamping direction, process supplement, sheet size and forming process parameters on the forming performance were systematically studied. Aiming at stamping forming of B-pillar tailored welded blank, the influences of variable gap pressing ring on weld-line movement and forming performance were studied. Based on the concept of knowledge-based engineering （KBE）, the body parts stamping analysis system and stamping process design interface of B-pillar were developed by using Microsoft Visual C＋＋6.0 and UG / Open API software. The forming process of B-pillar for the automobile was designed and simulated using stamping process design interface of B-pillar. The results show that the process design system can easily guide the design of B-pillar stamping process ,the simulation results meet the quality requirements of the part, and improve the speed of process design of B-pillar.
