摘　　要：针对目前计算机辅助公差设计软件的操作繁杂并且缺少装配尺寸链分析的现状,搭建了面向公差设计的装配信息数据结构,便于进行公差设计分析;在优化装配尺寸链生成算法的基础上,运用蒙特卡罗法进行公差分析,在主流的三维造型软件Creo平台上二次开发出了一套基于装配尺寸链自动生成的计算机辅助公差设计软件模块,并以实例验证了实用性。Based on the current computer aided tolerance design software operation is complex and lack of assembly dimension chain analysis of the status quo, this paper builds data structure for tolerance design of assembly information, to facilitate the analysis of tolerance design; on the basis of the generation assembly dimension chain algorithm of the optimization and used Monte Carlo method to tolerance analysis , developed a set of application software which based on assembly dimension chain automatic generation of computer aided tolerance design module , in the mainstream 3D modeling software Creo on the secondary development platform to achieve, and an example provided to testify the practicability .
