VIBRATION DAMPENING SYSTEM FOR DAMPENING VIBRATIONS IN A TURBINE COMPONENT CONFIGURED TO BE INSTALLED IN A FIRST BODY OPENING OF THE TURBINE COMPONENT AND TURBINE COMPONENT

A vibration dampening system (120) includes damper element(s) (174) in a body opening (160) of a turbine component (111). A resonant-tuned elongated body (190) extends through the damper element(s) (174) in the body opening (160). The elongated body (190) is configured to resonate at a predefined re...

Beschreibung
Zusammenfassung:A vibration dampening system (120) includes damper element(s) (174) in a body opening (160) of a turbine component (111). A resonant-tuned elongated body (190) extends through the damper element(s) (174) in the body opening (160). The elongated body (190) is configured to resonate at a predefined resonant frequency, such as the same resonant frequency as turbine component (111) at the body opening (160), to generate a force against the damper element(s) (174) in the body opening (160). The damper element(s) (174) have a surface (194) in contact with the body opening (160) and/or elongated body (190).
