Abstract

Abstract: The operational status of rotor systems is a critical factor in ensuring the stable operation of equipment.To evaluate the operational condition of the rotor system during equipment operation and to determine the nature and location of faults when rolling bearings fail,a rotor system status online monitoring system based on digital twin technology was proposed. Firstly,according to the operational characteristics of the rotor system,a digital twin framework for the rotor system was proposed. Then,the key technologies in the rotor system state monitoring method were analyzed. Finally,using a multifunctional rotor test bench as the digital twin entity,a rotor system status online monitoring system based on digital twin technology was built,verifying the feasibility of the rotor system digital twin framework,as well as the real-time performance and accuracy of the twin model. This provides a new approach for equipment fault prediction and health management.

Key words: digital twin, rotor system, surrogate model, online monitoring
