ABSTRACT:
A bumper/energy absorber system is resiliently mounted at the body mounting location to allow the bumper/energy absorber system to vibrate freely both vertically and in pitch at its natural frequency. The mounting spring rate is selected to use the dynamic energy of the bumper/energy absorbing system to attenuate steering column vibrations excited through the vehicle body structure by the shaking forces of the engine within a predetermined speed range. The mounting is designed to minimize bumper movement relative to the body from forces directly applied to the bumper from loads such as bumper jacking.
