Abstract:
1. An assembly for isolating an object from shock and vibration from an external source, comprising; (a) a cage surrounding said object, said cage operative to limit displacement of said object; (b) a plurality of springs coupled between said object and said cage, said plurality of springs operative to suspend said object from within said cage and to minimize mechanical coupling from said external source to said object, said springs being selected to set the resonant frequency of the assembly to a low spectral energy location; and (c) a plurality of dampers affixed to one of said cage and said object and dimensioned to be spaced away from another of said cage and said object in the presence of low amplitude vibration, said dampers shaped with a cross section that increases along their length from their distal end to their proximal end, and comprising a highly energy-absorbing material and operative to dissipate mechanical energy of said object with a progressively increasing deceleration following contact by said object or said cage, respectively, with one or more of said dampers; wherein said object is mechanically uncoupled from vibrations outside the system resonant frequency.
