Design and Realization of hybrid digital twin based on carbon steel corrosion

  •   Objectives  IoT technology is used to build up a digital twin model to comprehensively and directly reflect the corrosion process of metal structure in the whole life-cycle, realize the intelligent prediction and maintenance of metal corrosion, and improve the reliability of metal structure work.
      Methods  Combining a finite element model with a real-time data-driven model, a hybrid digital twin model of the atmospheric corrosion process and an experimental platform design scheme of IoT monitoring are proposed to establish a link between the corrosion digital simulation and the actual corrosion process.
      Results  A physical corrosion model is combined with a real-time data-driven corrosion model into a "hybrid digital twin" which can realize the whole life-cycle management of metal structures and
      Conclusion  The hybrid digital twin model combining real-time data-driven and physical models can provide references for corrosion research and the application of corrosion prevention technology.
