Methods for making damped load beams. |
摘要 |
<p>A damped load beam for a suspension assembly comprises a load beam and a damping structure. The damping structure comprises a layer of damping material bonded to the load beam and a relatively stiff constraining layer bonded to the damping material. The damped load beam includes undamped, opposed ends that are suitable for supporting other components associated with the suspension assembly. The method comprises the steps of providing clean, flat stock material for the constraining layer, applying a layer of damping material to at least a portion of the constraining layer stock material, providing clean, flat stock material for the load beam, and bonding the damping material to only a portion of the load beam stock material. A flat sandwich construction comprising the damping material intermediate the constraining layer stock material and only a portion of the load beam stock material results. The damped load beam is formed by stamping or chemically etching the flat sandwich construction such that a portion of the load beam stock material that does not have damping material thereon provides the undamped opposed end(s) of the load beam. <IMAGE></p> |
