Deformation Design Method Based on SBF Model

Abstract

The structure-behavior-function model is a kind of concept design model and we apply it to the deformation design mainly to express the design concept and design process.In this paper,the SBF model is used to express a complete design experience knowledge and is used as a node for design reasoning.We also add the non-axiomatic logic and a calculation algorithm of semantic similarity to the SBF model to accomplish the process of deformation design.Finally,  turbine blade is taken as an example to prove that the method can realize the deformation designing of parts. Meanwhile,non-axiomatic logic which is able to reduce the repetitive work of the designers is an effective way to simplify the designing.
