In this paper, the body in white （BIW） width dimensional consistency control methods had been carried on the concrete discussion and research. So the mechanism of virtual size parts were introduced in detail and the mechanism of the width of the BIW were analyzed. And this paper recommended the partial tolerance design method, DESIGN GAP design method and overlapping parts structure design method. Then the applications of these methods were explained to develop new product. The result that practiced control strategy to new vehicle practice showed： the BIW width dimensional consistency can be controlled within ±1.0 mm. The control strategy can realize the robust design of the new product dimension and enrich the company dimensional database.展开更多
白车身(Bady in White,BIW)宽度尺寸一致性直接影响着整车的内外饰美观度、风噪声以及安全性。对白车身宽度尺寸一致性控制方法进行探讨,介绍了零件实效尺寸机理,分析了白车身宽度尺寸机理,提出了偏公差设计方法、DESIGN GAP设计方法和...白车身(Bady in White,BIW)宽度尺寸一致性直接影响着整车的内外饰美观度、风噪声以及安全性。对白车身宽度尺寸一致性控制方法进行探讨,介绍了零件实效尺寸机理,分析了白车身宽度尺寸机理,提出了偏公差设计方法、DESIGN GAP设计方法和零件搭接结构设计方法等控制策略。以某车型侧围与下车体的Y向搭接为例,介绍了其控制策略的应用,为后续新车型白车身尺寸的稳健性设计提供了参考。展开更多
