摘要：
An apparatus for reducing vibration includes: a damping assembly configured to be fixedly attached to a downhole component, the downhole component configured to rotate within a borehole in an earth formation, the damping assembly having a damping frequency that is tuned relative to a selected natural vibration frequency of the rotating downhole component to reduce vibration due to component rotation.
