Abstract

Procédé pour introduire un désaccordage volontaire dans une roue aubagée d'une turbomachine déterminée de manière à réduire les niveaux vibratoires de la roue en réponse forcée, caractérisé par le fait qu'il consiste à déterminer, en fonction des conditions de fonctionnement de la roue à l'intérieur de la turbomachine, une valeur optimale d'écart type de désaccordage par rapport à la réponse maximale en amplitude de vibration voulue sur la roue, disposer sur ladite roue, au moins en partie, des aubes de fréquences propres différentes de telle sorte que la répartition des fréquences de l'ensemble des aubes présente un écart type au moins égal à la dite valeur de désaccordage.
