Abstract
A system and method for damping narrow band axial vibrations of a rotating device in which a reaction mass is coupled to the rotating device and a reaction mass actuator is employed to move the reaction mass axially along the rotating device. An effect of vibrations on the rotating device is then measured, and in response the reaction mass is moved axially to damp the effect of vibrations and so the vibrations.
