Abstract

Non-destructive testing (NDT) techniques have been explored and extensively utilized to help maintaining safety operation and improving ride comfort of the rail system. As an ascension of NDT techniques, the structural health monitoring (SHM) enables real-time condition assessment for mechanical civil, and transportation systems, without interrupting normal operation. Meanwhile, with long-term monitoring data collected from large systems in open environment, interpretating the large amount of data accompanied with great uncertainties and sophisticated data structure calls for advanced data-driven analysis methods to obtain comprehensive and systematic diagnosis. This presentation starts with introduction on SHM applications cases conducted by the speaker and research team in various scenarios, particularly railway systems, by using a federation non-destructive sensing techniques including vibration-based measurements, ultrasonic testing, electromechanical impedance, optic fiber sensing, etc., and developing corresponding sensor arrays/networks and monitoring systems upon them, followed by recent studies on computer-aided SHM integrating state-of-the-art machine learning algorithms and outlooks on future work aiming at establishing intelligent monitoring platform for other large scale systems involving interdisciplinary research and technology development.
