...Yunfeng Li; Chuang Liu; Xiaoxue Xue; Guochuang Wu Purpose This study aims to construct a thermo-mechanical-lubrication multiphysics coupling dynamic model for aero-engine bearings under the Digital Twin ( DT ) framework. It aims to realize high-fidelity simulation of bearing fault vibration...

... in prediction. In particular, it is shown that the procedure is capable of capturing the effect of ageing of two commercially available greases on their film thickness. Applying the proposed method in real time enables the development of digital twins of the associated machines. Originality/value The sensor...
