Reconfigurable modeling technology of similar-structure products configuration design

Abstract

The product configuration modeling is a key technology to realize configuration design. Most of the researches were mainly conducted focusing on how to establish a product configuration model, but were short of the consideration about the application scope and dynamic change features. In this paper, the reconfigurable modeling technology of similar-structure products configuration design is studied to enhance the generality and diversity of product configuration models, and to facilitate the dynamic upgrade of configuration models. The configuration components of products with similar structures are divided into sharable configuration components, essential configuration components and optional configuration components, so the construction of reconfigurable model of configuration design can be converted into the set operation of configuration components. The horizontal adjusting reconstruction of configuration model is carried out through the adding, replacing and deleting of configuration components, the vertical adjusting reconstruction of configuration model is carried out through the parametric deformation of configuration components, and the variable topological configuration model reconstruction can be realized through the transformation of partial structure of configuration components. Finally, NC machine products are used as an example to analyze and verify the reconfigurable modeling technology of products with similar structures. The speed of NC machine configuration design is found to be improved, and the number of NC machine configuration design models is decreased. And the reconfigurable design system of NC machine products is developed. The proposed modeling technology provides references for the processes, methods and steps of model reconstruction.

A method of categorization and organization for 3D model-based design knowledge

“…Most products are designed based on existing products in the enterprise [5]. Reference and reconfiguration of existing models will accelerate product design process as well as avoid numbers of designing errors.…”

Research on Rapid Design Method for Complex Product Based on General Structure Model and Reusable Parts Resource

“…Currently, the main theories or methods supporting the product rapid design are as follows [2][3][4]: the digital/virtual prototype design, the networked collaborative design, the modular design, and the intelligent design which is based on knowledge engineering and the derived variant design, configuration design and so on. Among them, the configuration design is realized on the basis of the standardized and generalized product structure model [5].…”
