Design and application of digital twin system for the blade-rotor test rig

Digital twin technology is a key technology to realize cyber-physical system. Owing to the problems of low visual monitoring of the blade-rotor test rig and poor equipment monitoring capabilities, this paper proposes a framework based on the digital twin technology. The digital-twin based architecture and major function implementation have been carried out form five dimensions, i.e. Physical layer, Virtual layer, Data layer, Application layer and User layer. Three key technologies utilized to create the system including underlying equipment real-time communication, virtual space building and virtual reality interaction have been demonstrated in this paper. Based on RS-485 and other communication protocols, the data acquisition of the underlying devices have been successfully implemented, and then the real-time data reading has been achieved. Finally, the rationality of the system has been validated by taking the blade-rotor test rig as the application object, which provides a reference for the monitoring and evaluation of equipment involved in manufacturing and experiment.

Automated summary

This paper proposes a framework based on digital twin technology to address the low visual monitoring and poor equipment monitoring capabilities of a blade-rotor test rig. The framework utilizes key technologies such as real-time communication, virtual space building, and virtual reality interaction to successfully acquire and read real-time data from the underlying devices. The rationality of the system is validated by using the blade-rotor test rig as an application object.
