依据产品概念结构设计中的公差进化模型和算法,结合由功能表面组成的功能模式研究了尺寸公差设计。给出了搜索局部尺寸链和全局尺寸链的方法,实现了概念设计阶段的尺寸公差设计的自动化,为以后的详细设计提供了参考。
According to tolerance evolving model and algorithm in conceptual structure design of the products, the dimensional tolerance design is studied combined with functional mode which is consist of functional surface; a solution to search a local or total dimension chain is given, the automation of dimension tolerance design is realized, a reference for the coming detailed design is provided.
