Abstract: To judge the remanufacturability of implementing mechanical parts remanufacturing,the overall framework of remanufacturability evaluation for mechanical parts was proposed.The failure condition of mechanical parts was determined based on fuzzy evaluation.The quantification methods of remanufacturability evaluation indexes including technical feasibility,economic feasibility as well as resource and environment index were presented,and the model of remanufacturability evaluation for mechanical parts based on quantified failure features was established.The proposed model was illustrated in a case of worm gear remanufacturing,and the result showed the better remanufacturability of this worm gear.

Key words: remanufacturability, failure features, mechanical parts, membership function

摘要： 为评判实施机械零部件再制造的可再制造度,提出机械零部件可再制造度评价的总体流程框架|基于模糊评判量化分析机械零部件的失效特征,并建立涵盖技术可行性、经济可行性和资源环境性三个方面的可再制造度评价指标体系及量化方法,进而形成一种基于失效特征的机械零部件可再制造度评价模型。结合蜗轮副再制造对所提出的模型进行验证分析,结果表明该蜗轮副具有较好的可再制造度。
