20120193846 | ADJUSTABLE VIBRATION ISOLATION AND TUNED MASS DAMPER SYSTEMS - Particular embodiments relate generally to vibration isolation systems and tuned mass dampers. In one embodiment, a vibration isolation system may include a supporting base, an isolated mass, at least one air mount, a control valve, a compressed air supply, and a supervisory controller. The air mount is positioned between the isolated mass and the supporting base. The control valve is pneumatically coupled to the air mount, the compressed air supply and the atmosphere, and is operable to adjust a flow of air to and from the air mount. The supervisory controller receives a mass relative height signal, a mass relative velocity signal, and a mass relative acceleration feedback signal corresponding to a relative acceleration of the isolated mass or a pressure of the air mount. The supervisory controller may control the control valve such that a mounting height, a damping and a stiffness level of the air mount are a function of the mass relative height signal, the mass relative velocity signal, the mass relative acceleration feedback signal, or combinations thereof. | 08-02-2012 |
