ABSTRACT:
A load support vibration isolation mount comprises first and second parts movable relative to one another with a gas cushion and a high pressure hydraulic fluid disposed in series between the parts to attenuate vibration induced force transfer between the parts. At least one porous elastic member and at least one sieve-like plate are arranged in stacked relation within the high pressure hydraulic fluid of the mount for absorbing energy from dynamic loading of the mount. Enhanced energy absorption and broader response characteristics for absorbing energy from dynamic loading of different frequencies are attained.
