PHM of Complex Engineering Systems – Methods and Applications

Prognostics and Health Management (PHM) is an important research direction in reliability engineering. With the large-scale deployment of sensors and the maturity of big data technology, PHM has been more and more widely used in complex engineering systems, and it has produced significant social and economic benefits. PHM generally includes the key tasks such as anomaly detection, fault diagnosis, health assessment, and remaining useful life (RUL) prediction. The new generation of machine learning methods represented by deep learning has played a central role in promoting the development of PHM in the big data environment. This report takes high-speed train key components and subsystems as examples, and presents the latest developments in our laboratory. These new methods have a certain degree of versatility, and can be extended to the key components of other types of engineering systems.
