移动公差在车身公差分配中的应用
Application of Excursion Tolerance Technology in Tolerance Assignment of Car Body Design
摘要
Abstract
In order to improve the assembling precision of car body, it is necessary to assign rational tolerance for stamping work-piece according to the car body structure in the design phase. In the paper, it expounded the importance of tolerance assignment of car body, discussed the application of tolerance assignment technology in car body design, gave detailed explanation for flowchart of tolerance assignment of car body, and proposed making use of excursion tolerance in some special structure according to the particularity. It has been applied to a certain car development case, and also its correctness has been verified. Under the precondition of satisfying assembling precision and technology specification, it worked out more reasonable tolerance. Therefore it can make development cost reduce, and decrease modifying frequency, as well as shorten the development cycle.关键词
