Abstract: As one of the important development directions of “Made in China 2025”,remanufacturing plays a huge role in resource recycle,reducing energy consumption and promoting transformation and upgrading of manufacturing.As a new technology,digital twin can fully connect and integrate the physical world and information world in real time,and can effectively promote the integration of informationization and industrialization in the shop-floor.Aiming at the uncertainties in the process of remanufacturing and the situation that information space of virtual remanufacturing and actual remanufacturing process can't be interactively integrated in real time,the digital twin was applied into the remanufacturing operation process,and the architecture for digital twin-based remanufacturing shop-floor was constructed.This architecture and it's operation paradigm were elaborated respectively,the application analyses for key technologies involved was made,and the remanufacturing operation paradigm for automobile based on digital twin in future was also explored.The application prospects for digital twin-based remanufacturing in related fields were discussed.

Key words: digital twin, remanufacturing, virtual remanufacturing, shop-floor architecture, operation paradigm, automobile

摘要： 再制造作为“中国制造2025”的重要发展方向之一,在资源再利用、降低能耗,促进制造业转型升级等方面发挥着巨大的作用。数字孪生作为一种能全面将物理世界与信息世界实时连接和交融的新技术,能有效促进车间生产作业信息化与工业化深度融合。针对再制造作业过程中的不确定性问题以及虚拟再制造信息空间和实际再制造过程无法实时交互融合的状况,将数字孪生应用到再制造作业流程,构建了基于数字孪生的再制造车间架构,对其架构组成及作业模式进行了描述,并对其中涉及的关键技术进行了应用分析,探究了基于数字孪生的未来汽车再制造作业模式。最后,探讨了基于数字孪生的再制造未来在相关领域的应用前景。
