Abstract

Die vorliegende Erfindung betrifft eine Schaufelanordnung mit Dämpfungselementen sowie ein Verfahren zur Vibrationsdämpfung einer Schaufelanordnung. Die Schaufelanordnung umfasst einen Rotor sowie am Umfang des Rotors angeordnete Schaufeln. Zwischen den Schaufeln sind Dämpfungselemente (2, 3) angeordnet, die bei einer Rotation des Rotors durch eine in radialer Richtung wirkende Zentrifugalkraft mit den Schaufeln in Kontakt stehen. Zwischen benachbarten Schaufeln sind hierbei zumindest zwei Dämpfungselemente (2, 3) in Umfangsrichtung des Rotors hintereinander angeordnet, die sich bei einer Rotation des Rotors über eine Berührungsfläche (6) berühren und von denen ein erstes Dämpfungselement (2) mit einer ersten Reibungsfläche (4) der einen und ein zweites Dämpfungselement (3) mit einer zweiten Reibungsfläche (5) der anderen Schaufel in Kontakt treten.
Mit der Schaufelanordnung lassen sich eine Vielzahl von unterschiedlichen Schwingungszuständen wirksam dämpfen.
