Abstract: The theoretical achievements and the technological perspectives achievements obtained through the national basic research program “Key Fundamental Scientific Problems on Mechanical Equipment Remanufacturing” were reviewed herein. The project used core parts of major mechanical equipment as the study objects, which were primarily the centrifugal compressors for the West to East Gas Transmission Project and heavy-duty engines. The major critical scientific issues were researched including the interdisciplinary of mechanical engineering, material engineering, mechanics, physics, chemistry and mathematics. The evaluation theories and atomic bonding between different materials were established for remanufacturability. An integrated remanufacturing system was established by proposing the competitive life analysis methodology, comprehensive evaluation methods and fundamental theories.

Key words: remanufacturing, centrifugal compressor, heavy-duty engine, control of shape and performance

摘要： 回顾了国家重点基础研究发展计划（973计划）“机械装备再制造的基础科学问题”项目实施过程中所取得的理论及技术突破。项目以大型机械装备的核心部件为研究对象，以我国西气东输工程中使用的大型离心式压缩机、重载发动机为主要研究载体，深入研究再制造领域中涉及机械、材料、力学、物理、化学及数学等多学科交叉的重大关键科学问题，创建可再制造性评价理论，创立异质材料原子间的键合原理，阐明再制造零件的竞争性寿命机制，构建面向再制造的决策基础理论与综合评价模式，为形成完整的再制造体系提供参考。
