摘　　要：针对产品主动再制造时其关键零件往往存在"提前再制造"或"滞后再制造"的问题,提出了寿命匹配函数的概念。通过研究不同特征结构参数组合下关键零件主动再制造时机的变化,建立了关键零件主动再制造时机与特征结构参数的映射关系,并引入寿命匹配因子作为寿命匹配完成的标志。提出了基于寿命匹配函数的主动再制造设计方法,根据寿命匹配函数,优化特征结构参数,实现关键零件与产品主动再制造时机的匹配。最后,以某型号柴油机为例进行寿命匹配,验证了该方法的有效性和可行性。In the processes of predecisional remanufacturing,the key components often had the problems of“early remanufacturing”or“delayed remanufacturing”,the concept of life matching function was put forward.By studying the changes of the predecisional remanufacturing timing of key components under different characteristic parameters,the mapping relationship between the predecisional remanufacturing timing of key components and characteristic structural parameters was established.And the life matching factor was introduced as the sign of life matching.A design method of predecisional remanufacturing was proposed based on life matching function.According to the life matching function,the characteristic structure parameters were optimized to realize the matching of the predecisional remanufacturing timing of the critical parts and the products.Finally,an engine was taken as an example for life match?ing,and the validity and feasibility of the method were verified.
