Active vibration control through sensing and controlling forces on an intermediate body
First Claim
1. A method of active vibration control including the steps of mounting a subject body on a supporting body by a mount which includes an intermediate body between the subject body and the supporting body, weakly vibrationally coupling the intermediate body to both of the said subject and supporting bodies, and, at least over a part of the frequency range for which control of vibrations is required, minimising vibrations of the intermediate body by the application of controlling forces to it, said forces being responsive to a single obtained by directly sensing vibrations of the 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.
