摘　　要：当前装配公差分析和设计一般是基于尺寸链原理,只考虑了装配零件的尺寸公差,并未考虑装配零件的形位公差,因此基于尺寸链原理的装配公差分析方法是有缺陷的。如何能使装配公差分析更贴近实际零件的装配是要解决的问题。基于图论知识和UG二次开发平台,对三维装配体模型建立装配链图,在此基础上查找零件几何公差的传递路径,为进一步探究零件几何公差的积累效应、装配体公差分析和综合应用做准备。The current assembly tolerance analysis and design generally depends on dimension chain principle. In this principle,the size tolerance of assembly parts is considered only without its shape tolerance. So the traditional modeling method based on the assembly tolerance of the dimension chain principle analysis is its drawback. This article needs to solve the problem that the assembly tolerance analysis is made more close to the actual parts assembly. Based on the knowledge of graph theory and UG secondary development platform,the assembly graph of the 3D assembly model is built and then the transfer path of the geometric tolerance is found out,in order to further explore the accumulation effect of the geometric tolerance,assembly tolerance analysis and synthesis.
