Abstract

Technique d'amortissement des résonances dans un système rotatif. On crée une représentation d'un mouvement vibratoire dans le système rotatif, on calcule la dérivée de cette représentation et l'on applique une force d'amortissement active déphasée dépendant de la dérivée du système rotatif pour amortir le mouvement.
