Abstract
A system for mounting a device on board ship which experiences normal vibrations of a predetermined frequency and which may be subjected to high intensity shock forces including a plurality of preloaded liquid springs operable in tension and compression and oriented in a truss configuration between the deck of the ship and the device, the casings of the liquid springs having a natural frequency in excess of the normal shipboard vibrational frequencies and by virtue of being preloaded providing rigid linkages for transmitting normal shipboard vibrational frequencies to the device, the preloading being of such a magnitude to permit the liquid springs to yield in either tension or compression when the ship is subjected to high intensity shock forces such as weapons effect pulses, and the liquid springs resetting the device to its normal position relative to the ship after termination of the high intensity shock forces.
