Abstract

This study aims at developing and implementing advanced time-frequency representation algorithms, i.e., Choi-William distribution, and cone-shape distribution, based on the spectrogram and the smoothed Wigner- Ville distribution to both improve time and frequency resolutions as compared with the spectrogram, and soothe interferences resulting from the Wigner-Ville distribution. Synthetic signals were designed to assess the effectiveness of these algorithms, and compare computing features of these schemes as well. A transmission-component test rig was built up to investigate dynamic characteristics of the gearbox, belt set and electro-magnetic brake during operation. Conducted experimentation highlights the justification of applying these advanced schemes in condition monitoring tasks of mechanical systems.
