| 摘 要： | 装配建模的实质就在于如何在计算机内有效地表达装配体外在的和内在的关系。在分析装配体几何实体信息模型、配合联接信息及设计约束机制的基础上,提出了一种以层次结构信息为逻辑主干,以拓扑联接信息为重要组成部分、支持产品全生命周期设计的广义装配模型的表达机制。该模型具有在数据结构与设计者的概念模型相同,便于理解,支持自上而下逐步求精的设计过程,便于装配模型根据需要进行修改和扩充,支持产品生命周期设计的全过程等特点。

| Abstract: | The essence of product assembly modeling is how to express the external and internal relations of assembly unit.Analyzing geometric modeling information of assembly unit,matching and connecting information and the constraint law of design,this paper puts forward a kind of general assembly modeling.This method is based on hiberarchy information of assembly unit,which is related to topological connecting information of assembly unit.It is designed to supporting product of lifecycle engineering design(LCED).There are the following advantages of this method:(1)Its modeling corresponds to the conceptual modeling of designer in data structure,which is easy for the designer to understand;(2)supporting the top-down design and the whole process of product LCED. |
