Abstract of presentation

Condition monitoring or ‘health’ monitoring of engineering structures and components, like vehicle frames and machinery parts, can be realized by various technologies, such as ultrasonic tests and dye penetrant inspection. Vibration analysis as a global condition monitoring method is studied in our research group and will be discussed in this research talk. Piezoelectricity is applied for self-powered sensing. First, Entropy-based vibration analysis for crack detection and localization will be introduced as a possible prompt for new threads in the field. Wavelet analysis as a ‘microscope’ of the perturbations in both time and spatial domains signals will then be discussed for high sensitive structural condition monitoring. In addition, a piezo-powered wireless damage detection solution will be presented. At last, some other research works/thinking will be shared for open discussion.
