摘要
再制造评价作为绿色再制造工程的设计基础,是开展再制造的前提。为了评价机械零部件的可再制造性,判断其是否适合进行再制造,基于层次分析法,提出一种以再制造相对加工指数为目标层的可再制造性评价模型;建立了涵盖技术、经济和环境三个方面的再制造评价指标体系及量化方法,并根据层次分析法确定各评价指标的权重,计算出再制造相对加工指数。以柴油机曲轴为案例,得到再制造相对加工指数为0.70,表明该曲轴可再制造性较好。
Remanufacturing evaluation is design basis of green remanufacturing engineering,and it is precondition of remanufacturing and key problem in remanufacturing research.In order to evaluate the remanufacturability of machine parts and determine whether it is suitable for remanufacturing,the remanufacturability evaluation model based on Analytic Hierarchy Process was proposed,in which the remanufacturing relative machining index was taken as target level.The model established remanufacturing evaluation index system and quantitative method covering three aspects of technology,cost and environment,and determined the weight of each evaluation index according to Analytic Hierarchy Process,and figured out the remanufacturing relative machining index.The proposed model was illustrated in a case of a diesel engine crankshaft,and the result showed the better remanufacturability of this diesel engine crankshaft.
