Abstract

PROCÉDÉ DE CONTRÔLE ACTIF DES VIBRATIONS D’UNE PIÈCE ET SYSTÈME ASSOCIÉ Un aspect de l’invention concerne un procédé de contrôle actif des vibrations d’une pièce structurelle (110) couplée à une source de vibration (16), comprenant : évaluer un état de santé de la pièce (110) ;déterminer une bande de fréquences des vibrations générées par la source de vibration (16) ;identifier au moins un mode de vibration de la pièce structurelle (110) à atténuer en fonction de son état de santé (K), chaque mode de vibration identifié étant compris dans la bande de fréquences des vibrations générées par la source de vibration (16) ;calculer une loi de commande (U) des transducteurs ; etatténuer, au moyen des transducteurs (31) suivant la loi de commande (U), l’amplitude de chaque mode de vibration identifié.
