Comportement vibratoire des pièces tournantes à l'aide de données sous-échantillonnées
2007
The technology named Tip-Timing enables to monitor the vibratory modes of bladed disks. A set of optical sensors is mounted on an engine casing in front of a disk and measures the times of arrival of every blade. These timings are then used to calculate the vibratory motions. Nevertheless, the obtained signals are undersampled and aliased. In this study, we will apply a spectral estimation which is designed to process this kind of data. Mots-clefs : Surveillance vibratoire ; Tip-timing ; Sous-echantillonnage
