Abstract
A vibration control apparatus designed specifically for use on space vehicles includes a stator for mounting in the vehicle, a lower flotor, magnetically levitated on the stator, an upper flotor nested in and magnetically levitated on the lower flotor, and position, orientation and motion sensors carried by the stator and flotors. When any changes in position, orientation or movement, i.e. vibration of apparatus is detected, magnetic force actuators are energized to compensate for such changes to keep a work platform on the upper flotor virtually vibration-free. Moreover, controlled and induced vibration of the work platform and an experiment carried thereby can be effected using the lower flotor as a reaction mass, i.e. without feedback to the vehicle.
