ABSTRACT:
Methods and apparatus for isolating a load structure from vertical, horizontal and rotational vibrations of a supporting structure operate with the aid of displacement of a pneumatic fluid from and to a fluid chamber of a pneumatic vibration isolation system. A fluid-tight diaphragm extends from a circumferential edge of the fluid chamber into that fluid chamber, and has a circumferential compliance section inside that edge of the fluid chamber. The diaphragm is structured inside of that compliance section with alternate stiffened and reinforced diaphragm portions in the fluid chamber. The diaphragm and the fluid chamber are coupled between the supporting structure and the load structure. Vertical vibrations are damped by displacing pneumatic fluid from and to the fluid chamber with the fluid-tight diaphragm and horizontal and rotational vibrations are damped with the reinforced diaphragm portion in the fluid chamber.
