Abstract:
A vibration control system for a structure having a first structural member and a second structural member, the vibration control system comprising:a liquid spring having a first volume of compressible liquid in a first chamber operably interposed between the first structural member and the second structural member using the compressible liquid to generate spring forces in response to relative displacement between the first structural member and the second structural member; a second volume of compressible liquid in a second chamber, the second volume remotely connected to the liquid spring by a fluid passage; a valve coupled to the fluid passage, the valve selectively operable to place the second volume in communication with the liquid spring; and a controller electrically coupled to the valve; wherein the controller emits a control signal to control the valve, the control signal being determined by a combination of at least a first component to alter the stiffness of the liquid spring and a second component to alter the damping of the liquid spring.
