[Abstract]:In today's world, with the rapid development of economy, the competition of mechanical products manufacturing industry is becoming more and more fierce, the manufacturing technology level is more and more high, and the product design cycle is getting shorter and shorter. Shearer is a complex machinery that integrates machinery, electricity and hydraulic pressure. Designing shearer quickly and efficiently to meet the needs of the market has become the key to the development of shearer manufacturing enterprises. In mechanical product design, reuse of existing design and deformation design of existing design occupy a large proportion. The efficient utilization of the design knowledge of shearer is very important to the design of shearer. This paper constructs the ontology model of design knowledge of shearer by improving the ontology construction method of seven-step method. The design knowledge representation of shearer is realized. Based on the ontology model of design knowledge of shearer, the knowledge base system and conceptual design system of shearer are established. Through analyzing and studying the composition and structure of the design knowledge of shearer, the design knowledge of shearer is divided into process knowledge by using the method of knowledge classification based on design process. Substantive knowledge and reasoning knowledge. Reduce and integrate the steps of the seven-step approach, and add the steps of design knowledge classification. A five-step method for modeling shearer ontology is designed. Based on the classification of design knowledge of shearer, the design knowledge ontology model of shearer is constructed. Prot 茅 g 茅 ontology modeling software is used. On the basis of the design knowledge ontology model of shearer, the design knowledge ontology of shearer is analyzed by Jena ontology analysis tool. This paper introduces the design knowledge of shearer stored in OWL document into relational database and forms the design knowledge base of shearer. By using dynamic network technology and database technology, the knowledge base system of shearer is developed to realize the inquiry and expansion of design knowledge. Ontology download and other functions. The ontology similarity and correlation calculation method is applied to the case similarity calculation of coal mining machine. A method for calculating the similarity of coal mining machine examples based on ontology semantic similarity is designed, in which the similarity degree of independent parameters is first calculated, and then the similarity is combined. The similarity of shearer is calculated. Based on the knowledge base of shearer design, the concept design system of shearer is developed. The design knowledge base system and conceptual design system of shearer are developed on the platform of ASP.NET, using Microsoft Visual Studio 2010 development tools, and selecting C # as the development language. SQL server 2008 is used as the backstage database. In the process of testing and using the system, the system has good interface, stable operation and reliable output result, which proves the reliability of the system.
