ABSTRACT:
A self-stabilizing system to protect sensitive equipment housed in a rack from shock forces emanating from the structure or foundation on which the rack is placed. The system includes a chassis restable on the foundation having an array of four vertical shafts anchored thereon. These shafts extend through bearings fitted in vertical ducts incorporated in the four corners of the rack whereby the rack is slidable on the shafts. Springs interposed between the base of the rack and the chassis or between the top of each shaft and the upper end of the duct in which the shaft is received, act to resiliently support the rack on the chassis and thereby attenuate the shock forces. Secured to the underside of the rack to raise it above the foundation are isolators whose stiffness characteristics are such as to resist rotational motion and to permit lateral motion.
