Component technology-based product modeling method

Abstract

The invention relates to a component technology-based product modeling method. The method comprises the following steps that: S1, hierarchically decomposing a product: decomposing the product into a hierarchical structure of components and / or parts according to a functional module; S2, abstracting attribute information of the components and / or the parts: performing attribute decomposition on the components and / or the parts in the aspect of geometry and non-geometry; S3, classifying the components and / or the parts in the product according to a similarity principle; S4, defining the components:abstracting generality information according to a classification result in the step S3, and defining the components and / or the parts respectively; S5, establishing a component database and importing the defined components into the database; and S6, calling and instantiating the components. The method has the advantages that: the similarity of the components and / or the parts in the conventional product model is computed and classified according to a similarity theory; redefinition of the components is avoided; and types and data volume of the component definition are reduced.

Description

technical field [0001] The invention relates to the technical field of product design, in particular to a product modeling method based on component technology. Background technique [0002] The rapid development of computer technology has brought new opportunities to the field of product modeling, various modern modeling methods emerge in endlessly, and the introduction of new technologies has greatly improved the efficiency of product modeling. Product design is a process of continuous innovation. By simulating the creative thinking process of the human brain, computer-based intelligent modeling technology can continuously accumulate design experience, automatically acquire new knowledge, and participate in new product design. The purpose of studying modern modeling methods is to shorten the product development time, make full use of existing resources, reduce costs, and improve the market competitiveness of enterprises. Different from computer integrated manufacturing, ...

AI Technical Summary

Problems solved by technology

Different from computer integrated manufacturing, agile manufacturing and other technologies that are oriented to the entire production stage of products, component technology focuses on the field of product modeling, aiming to solve the problems of complex product design and long cycle time

[0003] At present, research on rapid modeling of complex products mainly focuses on KBE (Knowledge Based Engineering) technology, modular technology, parameterization technology, and design reuse technology. Improvement, optimization, etc., modular design focuses on the reuse of design examples, provides relatively little design knowledge, and is difficult to adapt to product design with changing features
