Abstract
A mechanical linkage includes first and second end members and a pair of generally parallel arcuate beams, interconnecting the end members and defining a lateral space therebetween. A plurality of alternating fingers extend from each beam into the lateral space, and a damping member is attached between each adjacent pair of fingers within the lateral space.
Claims20
A method of manufacturing a damping structural member, comprising:
- attaching a pair of generally parallel, oppositely curved arcuate beams between end members of a damping linkage, in alignment with a load axis of the damping structural member, the end members being disposed at opposing longitudinal ends of the beams, the beams configured to laterally deflect away from each other under a compressive load applied to the end members, and to laterally deflect toward each other under a tensile load applied to the end members;
- attaching at least one finger to each arcuate beam, the fingers oriented generally transverse to the load axis and extending into a lateral space between the pair of beams in an alternating, interleaved configuration;
- and
- attaching a viscoelastic damping material between adjacent pairs of the fingers, the viscoelastic damping material configured to resist opposing lateral motion of the fingers due to the lateral deflection of the beams, to thereby absorb a portion of the axial load upon the mechanical linkage.

A method of manufacturing a damping structural member, comprising:
- aligning a pair of generally parallel, oppositely outwardly curved arcuate beams with a load axis of the damping structural member, with a lateral space between the beams;
- attaching end members to opposing longitudinal ends of the beams, whereby the beams laterally deflect away from each other under a compressive load applied to the end members, and laterally deflect toward each other under a tensile load applied to the end members;
- attaching a plurality of fingers to each arcuate beam, the fingers oriented generally transverse to the load axis and extending into the lateral space in an alternating, interleaved configuration;
- and
- bonding a viscoelastic damping material between adjacent pairs of the fingers, the viscoelastic damping material configured to resist opposing lateral motion of the fingers due to the lateral deflection of the beams, to thereby absorb a portion of the load upon the mechanical linkage.
