To solve the difficult problem of virtual and real fusion caused by multi-discipline, multi-physical quantity, multi-scale, dynamic time-varying and other factors in digital twin modeling, a high-fidelity modeling method of digital twin is proposed based on the operation process of contactor. The modeling method described and defined the model from three levels of geometry, mechanism and data. Based on the constructed model, the knowledge acquisition and data mapping process of the contactor's operation process were studied. Besides, to evaluate the validity of the built model, a fidelity evaluation method of the digital twin model is given. Case verification shows that the proposed digital twin high-fidelity modeling method is effective and the model can be evaluated.
