Active vibration control through sensing and controlling forces on an intermediate body

Abstract

A method and mounting for active vibration control of a vibrating body mounted to a supporting body, or vice versa, via a mounting which includes an intermediate body, wherein the intermediate body is substantially passively decoupled from the vibrating body and the supporting body, at least over part of the frequency range over which vibrations are to be controlled, and over said at least part of the vibration frequency range compensating forces are applied to the intermediate body in response to vibrations detected within it.
