Refurbishment and remanufacturing play a vital role in
the sustainability of the large industrial field, which aims at
restoring the equipment that is close to the end of their life.
The EU-funded project RECLAIM proposes new approaches
and techniques to support these two activities in order to
achieve saving valuable materials and resources by renewing
and recycling the mechanical equipment rather than
scraping them when they exceed the end of the lifetime. As
the most critical part of predictive maintenance in RECLAIM,
the fault diagnosis technique could provide the necessary
information about the identification of the failure type, thus
making suitable maintenance strategies. In this paper, we
propose a novel implementation method that can combine
the digital twins with the fault diagnosis of large industrial
equipment. Experiment result and analysis demonstrate
that the proposed framework performs well for the fault
diagnosis of rolling bearing.
