Abstract
Digital twin uses digital technologies to describe and model the characteristics, behaviors, and processes of a device or a system in real world, which has aroused wide concern in aerospace engineering, smart factory and smart building. This paper inspected the various definitions and characteristics of digital twin, and summarized the perspectives and process when using digital twin in PHM area. A digital twin–driven PHM framework of high–speed railway (Electric Multiple Unit) EMU maintenance has been proposed.
