Abstract: A vibration control system for a structure having a first structural member and a second structural member. The vibration control system having a liquid spring operably interposed between the first structural member and the second structural member. The liquid spring uses a 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 is removably connected to the liquid spring by a fluid passage. A valve is coupled to the fluid passage. The valve is selectively operable to place the second volume in communication with the liquid spring. A controller is electrically coupled to the valve. The controller emits a control signal to control the valve. The control signal is 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.

Abstract: A vibration control system for a structure having a first structural member and a second structural member. The vibration control system having a liquid spring operably interposed between the first structural member and the second structural member. The liquid spring uses a compressible liquid to seamlessly generate spring and/or damping forces in the suspension system in response to relative displacement between the first structural member and the second structural member. A second volume of compressible liquid is located in a second chamber. The second volume is removably connected to the liquid spring by a fluid passage. A valve is coupled to the fluid passage, the valve selectively operable to place the second volume in communication with the liquid spring. A controller is electrically coupled to the valve. The controller emitting a control signal to control the valve.
