【摘要】 为实现概念结构与公差并行设计,提出了基于功能表面的公差表示模型。以功能表面、功能表面最小基准元等概念为基础,结合面向对象的思想,将现有的公差类型进行合理分类,并对类属性进行了深入研究。经实例验证,该模型能够表示功能表面的公差信息。更多还原

【Abstract】 According to the requirements of concurrent design of conceptual design and tolerance design,tolerance representation model based on function surface was studied.The tolerances were classified and studied with OOT methodology comprehensively based on the concepts of function surface and function surface minimum datum elements.A case indicates that this model can represent the tolerance information of function surfaces.更多还原
