A device (19) for generating a rotating force vector and an oscillatory couple includes a plurality of non-concentric eccentric masses (22A, 22B, 22C, 22D, 22E, 22F) co-rotating at the same angular speed; and means (24A, 24B, 24C, 24D, 24E, 24F) for individually controlling the angular position of each of the masses; whereby, by selectively controlling the angular position of each eccentric mass, the device may generate a desired rotating force vector and a desired oscillatory couple. In use, the device performs an improved method for opposing the propagation of vibration from a dynamically unbalanced rotating rotor through a supporting structure (12). This method comprises the steps of: mounting a plurality of non-concentric rotatable eccentric masses on the supporting structure; co-rotating each eccentric mass at the same angular speed as the rotor, and controlling the angular position of each mass relative to the angular position of the rotor; thereby to generate a pattern of rotating inertial forces to oppose the transmission of vibration from the rotor through the supporting structure.

A device for generating a rotating force vector and an oscillatory couple, comprising: a plurality of non-concentric eccentric masses co-rotating at the same angular speed; means for individually controlling the angular position of each of said masses; said plurality including a first pair of masses, the relative angular position of the masses of said first pair being maintained 180°apart; and said plurality including a second pair of masses, the relative angular position of the masses of said second pair being controlled to produce an adjustable-amplitude rotating force vector such that by selectively controlling the angular position of each eccentric mass, said device will generate a desired rotating force vector and a desired oscillatory couple. A method of opposing the propagation of vibration from a dynamically unbalanced rotating rotor, which reacts on a supporting structure with a rotating force vector and an oscillatory couple, comprising the steps of: mounting a plurality of non-concentric rotatable eccentric masses on said supporting structure; co-rotating each of said eccentric masses at the same angular speed as the rotor; and controlling the angular position of each of said masses relative to the angular position of said rotor so as to generate an opposing rotating force vector and an opposing oscillatory couple on said supporting structure.
