再制造毛坯是退役后的产品,其零部件存在状态不确定的问题,无法实现产品中配合零件的最佳利用,针对该问题提出了基于寿命匹配的零部件再制造优化设计方法。通过分析产品失效中所存在的"短板效应",提出了零部件寿命均值匹配和倍数匹配的寿命匹配模式,并给出了相应的寿命匹配方法;建立了设计信息与服役特性映射模型及基于该映射模型的反馈设计机制;最后,以曲轴-轴套系统为例进行寿命匹配,对其初始设计参数进行面向再制造的改进,验证了所提方法的有效性和可行性。
Remanufacturing blanks were retired products and the component status was uncertain,the components could not achieve the best use.For the problem,this paper presented components optimization design for remanufacturing based on life matching.Through the analyses of the existence of"short board"effect in the product failure,the mean and multiple matching were established,and also the corresponding matching means.The design information model,performance feature model and their interaction and feedback model were presented.Finally,crank-bush life matching and the improvement of the initial design due to remanufacturing were carried out to verify the effectiveness and feasibility of the method.
