Beschreibung
Zusammenfassung:	A vibration damping device for a blade of a rotary machine according to an embodiment of the present invention is provided with: one or more housings configured so that the housings can be housed in a cavity formed below the platform of the blade and so that the housings are mountable to and removable from the blade; and damping materials provided in vibration damping spaces formed in the housings. Un mode de réalisation de la présente invention concerne un dispositif d'amortissement de vibrations pour une lame d'une machine rotative comprenant : un ou plusieurs boîtiers conçus de telle sorte que les boîtiers peuvent être logés dans une cavité formée au-dessous de la plateforme de la lame et de sorte que les boîtiers peuvent être montés sur la lame et retirés de celle-ci ; et des matériaux d'amortissement disposés dans des espaces d'amortissement de vibrations formés dans les boîtiers.
