基于装配的产品信息模型研究

A products model based on assembly in the conceptual design

本文提出了一种基于装配信息的产品概念设计建模方法。该模型采用了面向对象技术 ,将概念设计中的物理元素及其它实体用对象表达 ,通过对象间关系的建立来描述产口的装配信息。为了适应设计过程中频繁修改装配模型 ,用基本类构成装配模型的结点 ,用散列表生成结点的索引项 ,并利用实例推理技术 ,实现实例对象的快速查询。

The paper presents a new assembly model for the conceptual design of products. The main idea is that the physical elements of a conceptual design, its parameters and properties are represented as objects and their attributes and these objects are combined to form an assembly and then case-based reasoning techniques are adopted. The hash table is introduced. Compared with existing model, the model is easy to be encoded and therefore the reasoning can be successfully applied. The object-oriented case techniques make the case more powerful.
