Abstract

As a key rotating component for power transfer in an aeroengine, the reliability of the turbine disc plays a decisive role in operational safety. Since monitoring, detection, prediction and decision making are not yet available for its life design and evaluation technology, digital twin technology is applied to its life management. Firstly, according to the functional requirements, the framework of the digital twin system for life management is clarified; secondly, in the model layer and application layer, the design of the system is completed to realize the virtual mapping of physical entities; finally, through application examples, it is shown that this system can realize the functions of online monitoring, signal control and life prediction to optimize the operation and maintenance.
