Abstract: Due to the intercoupling relationships between functional structures,the component's performance might be degraded with optimizing the several local structures in design stage of remanufacturing.To deal with this issue,the concept of structure coupling matrix was presented.The structure coupling function matrix was established to express the mapping relationships between structural strength and structural characteristic parameters,and the structure influence factor matrix was given to present the impacts of structural characteristic parameters on structural strength.Based on structure coupling matrix,optimization design method of predecisional remanufacturing was proposed to improve the component's overall performance.One 6L240 engine crankshaft was studied as an instance to validate the effectiveness and feasibility of this method.

Key words: structure coupling, predecisional remanufacturing, structure coupling matrix, optimization design, remanufacturing, product design
