Abstract
A system for reducing vibration in a wind turbine includes a mass structure having at least one hole extending therethrough; a rod having a top threaded portion, an upper level stop disposed on or below the threaded portion, and a fixed lower level stop disposed below the upper level stop. The mass structure has a designed weight and shape that, in combination with the adjustable axial distance between the upper level stop and the lower level stop, is designed to provide a properly tuned system for a particular frequency. A base having an aperture designed for receipt of the lower level stop therein is configured for attachment to a component of the wind turbine.
