Apports de la cyclostationnarité à l’analyse des signauxmécaniques
Published online by Cambridge University Press: 15 June 2010
Abstract
La cyclostationnarité, propriété propre aux processus dont les caractéristiques évoluentcycliquement au cours du temps, offre un cadre particulièrement adapté à l’analyse denombreux signaux acoustiques et vibratoires. Après avoir rappelé les spécificités del’approche cyclostationnaire dans le contexte mécanique, nous montrons à travers plusieursexemples les possibilités qu’elle autorise dans des domaines d’application liés audiagnostic des machines, à l’identification des systèmes mécaniques et à la séparation desources vibro-acoustiques.
