摘要:

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。

关键词: 再制造毛坯, 寿命匹配, 再制造优化设计, 服役特性

Abstract:

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.

Key words: remanufacturing blank, life matching, remanufacturing optimization design;performance feature
