The power transmission train is the fundamental and most critical mechanical part in a rotating machine, the malfunction of which can lead to a complete breakdown of a mechanical system and even a substantial economic loss if unattended. In a power transmission train, key components such as gearboxes and bearings are vulnerable due to the long-term exposure to heavy load, high rotating speed, high temperature and other harsh working conditions and are prone to failure due to accumulated health degradation and stress concentration. Therefore, it is important to have a continuous condition monitoring programme in place to ensure the safe operation of these components. Many fault diagnostic and prognostic techniques have been developed over the past few decades aiming to improve the reliability and to extend the useful lifespan of these mechanical components. This talk presents an overview of various signal processing and data-driven techniques developed and some relevant research works undertaken by our group in this field. Case studies are also presented in the talk to outline the practical and potential future industry applications of these techniques.
