Embodiment Construction

[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0067] Embodiments of the present invention and its implementation process are as follows:

[0068] As a heavy-duty basic equipment in the machinery industry, large hydraulic presses play a pivotal role in steel, automobile, chemical, electric power and other industries. In this embodiment, the ontology of a hydraulic machine is taken as an example, and an associated information model is built on the ontology structure, so as to verify the effectiveness of the proposed method.

[0069] The body mechanism of a hydraulic press is generally composed of a frame, a moving part of a hydraulic cylinder and a guide device. The body structure bears the vibration during the operation of the hydraulic press and the weight of the whole machine, so it should have reasonable strength, stiffness and guiding accuracy during the design process, and it should ...

Abstract

The invention discloses a design intention-oriented product correlation information modeling method. Based on a fuzzy set theory, establishment and quantitative expression of multiple constraint criterions are performed according to a correlation relationship among product parts; each constraint correlation is assigned with a triangular fuzzy number; a part identification frame with the multiple constraint criterions is established; data is extracted from a design knowledge database and is subjected to analysis processing in a multiple constraint criterion sorting fusion mode; a final evidence body of multiple constraint criterion fusion is obtained; fuzzy correlation intensity is defuzzified; comprehensive correlation intensity of products is obtained; and a quantitative product design structure matrix is formed. The method has the advantages of high design accuracy and accordance with a design intention for the problem that the design intention cannot be accurately expressed due to fuzzy and incomplete correlation data in a conventional complicated product correlation information modeling process.

Description

technical field [0001] The invention relates to a design intention-oriented product association information modeling method, which belongs to the field of product design. Background technique [0002] In order to meet the ever-changing individual needs of users for product performance and quality, manufacturing companies often need to carry out adaptive operations such as transformation and maintenance of their products. Complex products are composed of mechanical, electronic, hydraulic, control and other system couplings, and different subsystems are composed of many interrelated parts. In order to optimize operations such as module division and reconstruction of complex products, it is first necessary to complete product association Information modeling work. [0003] In the traditional modeling process of product related information, the relationship between product parts is usually represented and calculated by means of language variable evaluation and linear weighting....
