摘要
提出了一种基于装配拓扑树的产品结构模型,在此基础上构造了面向对象的产品模型类,并通过事物特性表技术实现从零部件类到零部件实例的转化,从而完成产品及其零部件的变型设计。本研究以CATIAV5为平台,将事物特性表技术和约束变型规则相结合,应用于某航空企业的工装快速设计中,并以型架为例给出了产品快速变型设计的过程,验证了所提出的产品结构模型的有效性。
A product structure model based on the assembly topology tree is put forward. Based on this, the object-oriented product model classes are built up. By using tabular layouts of article characteristics technique, the transformation from part classes to part examples is realized, so the variant design of product can be carried out. Associated with variant rules and tabular layouts of article characteristics technique, aircraft tooling's fast design system on the CATIA V5 software platform is used in a large aviation enterprise. And a case illustrating practicability of product variant design is verified.
