| Abstract: |
| It directly affects the inner and outer aesthesis, wind noise and safety of the vehicle to the BIW width dimensional consistency. 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. |
