Embodiment Construction

[0025] The product gene modeling method based on the behavioral semantic network knowledge model includes the following steps: 1) Establishing the behavioral semantic model of the product; 2) Establishing the mapping criteria between the product’s behavioral semantics The mapping criterion of semantic predicates establishes the description frame scheme of the functional and geometric features of the product; 4) transforms the description framework scheme described in step 3 into the corresponding gene code by applying evolutionary design and gene coding technology, and establishes the functional gene model of the product.

[0026] Wherein, the behavior semantic model adopts a three-dimensional DOF Cartesian coordinate system, and its three DOF direction axes are respectively: normal axis, horizontal axis and longitudinal axis; the behavior semantic predicate has eight in total, which are respectively : Occlusion, connection, translation, rotation, fixed position, coverage, asse...

Abstract

The invention provides a product gene modeling method based on a behavior semantic-network knowledge model, which comprises the following steps: (1) a behavior semantic model of the product is built; (2) a mapping rule between the behavior semantic model of the product and a behavior semantic predicate is built; (3) a frame description proposal of the functional character and the geometrical characteristic of the product according to the mapping rule between behavior semantic model and the behavior semantic predicate; (4) the frame description proposal described in the step (3) is transformed into a corresponding gene code by applying the evolutionary design and the gene code technology, and a functional gene model of the product is built. Based on the code manner, the built functional model establishes a good basis for the evolutionary design and the automated innovation of the product, and fully prepares for further researches in the future.

Description

【Technical field】 [0001] The invention relates to a knowledge modeling method in the design field, in particular to a product gene modeling method based on a behavioral semantic network knowledge model. 【Background technique】 [0002] It is generally believed that the design phase will occupy most of the cost of a product development cycle. However, in the past, product designers would pay too much attention to product performance and a single functional index, which resulted in insufficient self-adaptation and self-optimization of the product design process, rigid design process and lack of creativity. In recent years, with artificial intelligence being continuously introduced into the design field, product design is gradually developing towards intelligence, and the research on intelligent design has attracted more and more attention. Intelligent design is to solve design problems through design-based expert systems and man-machine intelligent design systems. It is the ap...
