Abstract: The generalized growth and remanufacturing of waste mechanical products is a multi-level and multi-particle remanufacturing process from waste mechanical products to performance improvement,function expansion,or appropriate reuse. There are many kinds of feasible product sets for generalized growth and remanufacturing of waste mechanical products,the product information is complicated and the information connection is poor,which affects the retrieval and selection efficiency and accuracy of waste mechanical products and their parts remanufacturing target products. To solve the problem,a modeling method of waste mechanical product information based on fusion semantic information was proposed. Considering the correlation between parts in waste mechanical products and the material,structure,and failure information of the parts themselves,integrating semantic information and topological graph theory,the product information that affects the selection of generalized growth and remanufacturing can be accurately described and integrated into the product information graph. Through the case of parts retrieval,the validity of the proposed product information model was verified by comparing it with the existing information model.
