Abstract: To solve the product design knowledge database search problem in intelligent design methods, a search method for design knowledge database based on ontology mapping was proposed. To describe complex product design knowledge, the design knowledge database was set up by the ontology-based knowledge presentation. The product design schemes searching problem were transformed into ontology mapping problem and product design schema satisfying the design requirements was found in the ontology knowledge database through the ontology mapping algorithm. A new ontology mapping algorithm which integrated the element level and structure level mapping technologies was designed and applied to this intelligent design method. Finally, the correctness and validity of the search method was tested and verified by the flight control actuator design example.

Key words: ontology, mapping, case-based reasoning, flight control actuator, product design
