ABSTRACT:
A dynamic absorber device for absorbing undesirable vibrations and resonances in dynamic machines, such as disk drives, is formed with a viscoelastic link element, an absorber base and an absorber mass. The link element is disposed between the absorber base and the absorber mass to absorb vibratory forces, and to minimize the effects of bending and deformation. The absorber device is assembled to disk drive components, such as the base casting or carriage, to effectively reduce vibrations, undesirable resonances and noise.
