ABSTRACT:
A self-positioning shock and vibration isolating suspension system is disclosed which incorporates one or more pneumatic mounts for supporting a load on a base. Each pneumatic mount comprises a hollow elastomer body with a diaphragm at each end, means for connecting one diaphragm to a base and the other to the load, means for pressurizing the elastomer body with a fluid so that the diaphragms and the fluid acting thereon form a pneumatic spring having a spring stiffness less than that of the hollow body, and means for varying the fluid pressure within the elastomer body in accordance with changes in the magnitude of the load.
