Abstract
Apparatus for both attenuating vibrations below a given load and absorbing shock above the given load. A hydraulic damper unit is equipped with a spring that preloads the device and positions the damper in a neutral or centered position. The spring holds the damper unit centered until the preload force is exceeded in either tension or compression. Elastomeric rod ends connect the damper unit to a mass to be protected and a supporting structure. The elastomeric rod ends have a response such that they attenuate vibrations up to the preloading force of the spring whereupon the elastomer is fully compressed thus permitting the damper to be displaced to absorb shock loads that are greater than the preload break-away force.
