Abstract
A vibration reduction system is provided for use in conjunction with a rotational device including a stationary body, a rotating body, and a first bearing assembly disposed between the stationary body and the rotating body. The vibration reduction system includes a first plurality of bearing mount actuators residing between the stationary body and the first bearing assembly. The first plurality of bearing mount actuators is configured to adjust the radial position of the first bearing assembly. The vibration reduction system further includes a vibration sensor, which is coupled to the stationary body, and a controller, which is coupled to the vibration sensor and to the first plurality of bearing mount actuators. The controller is configured to reduce vibrations sensed by the vibration sensor by selectively adjusting the radial position of the first bearing assembly utilizing the first plurality of bearing mount actuators.
