Abstract

A vibration damping system (120) includes a vibration damping element (166) for a turbine nozzle (112) or blade (114). A body opening (160) extends through the turbine nozzle (112) or blade (114) between the tip end (132) and the base end (130) thereof, e.g., through the airfoil (134) among potentially other parts of the nozzle (112) or blade (114). A vibration damping element (166) includes a plurality of stacked plate members (170) within the body opening (160). Each plate member (170) is in surface contact with at least one adjacent plate member (170) to cause friction that dampens vibration of the nozzle (112) or blade (114). The body opening (160) has an inner dimension and each plate member (170) has an outer dimension sized to frictionally engage the inner dimension of the body opening (160) to damp vibration. Plate members (170) may each include a central opening (180) therein, and a fixed elongated body (186) may extend through the central opening (180).
