Seamless control of spring stiffness in a liquid spring system

摘要

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.
