摘要: 再制造是再循环的最佳形式,但被动再制造毛坯数量和质量上的不确定阻碍了再制造工程的产业化。针对目前研究中仍存在的问题,提出主动再制造的概念,在分析产品再制造与其寿命周期的关系基础上,阐述主动再制造理论,介绍主动再制造中的相关概念,归纳主动再制造的主要特征。同时为了更加合理地实现主动再制造,针对产品中零部件间的关系,进行主动再制造设计的探讨,建立主动再制造设计理论与设计方法框架,阐述主动再制造设计的基础理论和基本流程,并且对应于主动再制造设计中的产品级设计、零部件级设计和结构级设计分别提出了寿命匹配、结构功能梯度和冗余强度,并进行了综合分析。以发动机曲轴-连杆系统为例,进行了主动再制造设计,结果表明,提出的设计理论与设计方法是有效、可行的。

关键词: 结构功能梯度, 冗余强度, 寿命匹配, 主动再制造

Abstract: Remanufacturing is the ultimate form of recycling. However, the uncertainties in quality and quantity of cores in reactive remanufacturing hinder the industrialization of remanufacturing. To meet with the issues, the concept of proactive remanufacturing is put forward. Based on the relationship between remanufacturing and the lifecycle of products, theories of proactive remanufacturing are expounded. Besides, the relevant concepts in proactive remanufacturing are presented, and the principal characters of proactive remanufacturing are concluded. Then, in order to realize proactive remanufacturing more reasonably, design for proactive remanufacturing, which aims at optimizing the relationship of components, is discussed. The structure of design theories and methods for proactive remanufacturing is established. The fundamental theories and basic process of design for proactive remanufacturing are presented. Meanwhile, the concepts of life matching, structural functionally gradient and residual strength, which respectively correspond to the design of product level, component level and structure level, are proposed. Finally, designs for proactive remanufacturing are demonstrated by taking the system of crankshaft and connecting rod for an example. The results show that, the design theories and methods are valid and feasible.

Key words: life matching, proactive remanufacturing, residual strength, structural functionally gradient
