Beschreibung
Zusammenfassung:	A support for machinery, and for isolating vibration from the machinery, comprises a plurality of mounts, each mount comprising an elastomeric block for completely supporting the static load of the machinery, and active isolation means comprising inertial shakers arranged to maintain essentially a zero stiffness of the mount to excited structural resonances over a desired frequency band above said mount resonant frequency, and to modify the transmission of out of balance forces to the hull. A control system coupled to the inertial shakers includes a means for applying damping force signals, such as to dampen structural resonances, to inhibit the onset of resonant vibration.
