摘　　要：针对再制造设计过程中优化零件某一薄弱结构可能导致零件整体性能劣化的问题,对零件结构间的耦合关系进行了研究。提出了结构功能耦合系统概念,建立了结构功能耦合系统模型,用结构影响因子表达结构耦合程度。在此基础上,给出了主动再制造在零件层级的设计方法,实现了零件全生命周期内整体性能的提升,并以发动机曲轴为例进行了方法验证。Aiming at the problems that a weak structure of optimization parts might lead to deterioration of the overall performance for parts in the design processes of remanufacturing,the coupling relationship between the structures of parts was studied.The concepts of structure function coupling system were proposed,the model of structure function coupling system was established,the structure coupling degree was expressed with structural influence factors.Then,the design method of predecisional remanufacturing was given in the part levels,and the overall performance of parts was improved in the whole life cycle,and the engine crankshaft was taken as an example to verify the method.
