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