基于联接元的机电产品再制造拆卸结构再生设计方法研究

To realize the knowledge supporting to the process of electromechanical product design for remanufacture and increase the quality and efficiency of product development the project about remanufacturing disassembly structure regeneration design for electromechanical products based on connection units is presented. The part is considered as the minimum unit of product traditionally, which has some limits in remanufacturing disassembly structure regeneration design (RDSRD).The parts combination connected by physical, chemical or mechanical method is defined as connection unit. Thus the product is the organic combination of connection units. Based on the connection unit and remanufacturing disassembly knowledge, the RDSRD method is presented in this project. Main research contents of the project include the modeling of connection unit with remanufacturing disassembly information and it's interchange and reconstruction method, the remanufacturing disassembly structure mapping technology based on derivation of connection units，the remanufacturing disassembly structure change response based on reuse of connection units, visual feedback of the electromechanical product's remanufacturing disassembly performance, etc. Finally, a RDSRD system of electromechanical products is developed and some cases are studied to verify the feasibility of the presented methods in the project..The new academic achievements are gained in electromechanical product remanufacturing disassembly structure regeneration design theory, the remanufacturing disassembly structure change response method based on reuse of connection units and the visual feedback technology of the electromechanical product's remanufacturing disassembly performance in the project..Studying of the project is of significance for the improving of electromechanical products' remanufacturability, remanufacturing cost reduction, energy saving and emission reduction, and so on.
