Abstract
A damping structure for providing damping and vibration attenuation includes an intermediate steel sheet positioned between an upper steel sheet and a lower steel sheet. The structure is incorporated as a part of a suspension component. The intermediate sheet is perforated with a plurality of holes, and a plurality of elastic strips are positioned between each of the sheets when assembled. The edges of the sheets are welded, sealing viscous fluid within the structure. Alternatively, the structure can be secured by rivets. Compression on the damping structure moves the fluid through the holes, providing a damping effect.
