装配顺序生成是装配设计自动化中的一个重要而复杂的问题。本文在分析现有装配模型的基础上，引入虚拟子装配体的概念，提出了装配层状关系模型，采用割集法和与／或图产生可行装配顺序，给出了二级圆柱齿轮减速器装配工艺规划的应用实例。
Assembly sequence generation is an important and complex issue in assembly design automation. Based on the analysis of the existing assembly models, this paper introduces the concept of virtual subassemblies and puts forward the layered model of assembly. The cut assembly method and / or graph are used to generate the feasible assembly sequence. The two-stage cylindrical gear reducer Application example of assembly process planning.
