Embodiment approach

[0077] The "design module" of a function or solution can have two specific implementations, examples are as follows:

[0078] a) Using the spreadsheet as the design module, using the spreadsheet to establish the calculation formula in the detailed scheme design process, to complete the conventional scheme parameter design calculation function, and to store the design requirement parameters, design result parameters and scheme design calculation formulas in the design module respectively To the corresponding cell of the spreadsheet, replace the design parameters in the formula with the address of the cell or the name of the cell, and the content in the associated parameter table can be automatically updated according to the output of the spreadsheet cell, such as Figure 5 shown;

[0079] b) For complex design analysis or knowledge processing processes such as scheme selection reasoning, numerical calculation, parametric drawing, etc., use high-level language to write design an...

Abstract

The invention discloses a knowledge modeling method and system used for aided design of a mechanical product scheme. The method comprises the steps of firstly performing overall function scheme designknowledge modeling to build a function-scheme template tree knowledge model and a function scheme design example model; and secondly establishing function or scheme design modules, establishing association with a function-scheme template tree, building a check function scheme design model and a parameter reasonability scheme check rule, combining the design modules in the form of a reconfigurablemodule process or task process, building a scheme design process model, and realizing parameter value automatic transmission and design process guide functions. The system comprises a function schemeaided design module, a module process aided design module, a task process aided design module, a design module control module and a system main control module. According to the method and the system,the knowledge modeling difficulty can be lowered; and the knowledge modeling method and the corresponding aided design system which conform to thinking habits of engineers and are reusable are provided.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, in particular to a knowledge modeling method and system for mechanical product scheme-aided design. Background technique [0002] At present, enterprises have basically realized the automation of engineering drawings and drawing, but the degree of automation in the design and analysis of mechanical product schemes is very low, and they still rely heavily on the experience of engineers. In view of this, the product solution design technology based on knowledge engineering (KBE) is produced, which aims to store and reuse the enterprise's product solution design knowledge, and automate some tedious and repetitive work in the product solution design process, thereby improving the product design efficiency. and quality. In order to establish a product scheme-aided design system that meets certain (or certain) product design requirements, it is necessary to first establish a knowledge mo...
