摘要:
A vibration damping device (10) for stringed racquets (12) including a viscoelastic member (22) adapted to be mounted between strings (16) of the racquet (12) and at least one movable member (24) carried on the viscoelastic member (22). The movable member (24) is movable relative to the viscoelastic member (22) in response to vibrations induced by an impact on the strings (16) of the racquet (12) such that the vibration damping device (10) vibrates over the same frequency range but out of phase with the racquet (12) to dampen vibrations in the racquet (12).
摘要:
A damped laminated metal structure includes a first sheet of material defining a first surface, a second sheet of material defining a second surface, a bonding material extending between the first surface and the second surface to bond the first sheet of material to the second sheet of material, and a plurality of reinforcements disposed in the bonding material between the first surface and the second surface to reduce effects of creep to a minimal extent and increase torque retention capabilities of the damped laminated metal structure.
摘要:
A golf club (10) having a vibration damping device including a club head (12), a shaft (16) connected to the club head (12) having resonant frequencies over a predetermined range and a rod (20) disposed within the shaft (16) with a viscoelastic material (22) interposed between the shaft (16) and the rod (20). The rod (20) is flexible and has resonant frequencies over the same frequency range as the shaft (16) such that the shaft (16) and rod (20) vibrate out of phase with respect to each other and thereby deform the viscoelastic material (22) to damp vibrations in the shaft (16).
摘要:
A multi-mode vibration absorbing device for implements includes a base member and a mass mounted to the base member and cantilevered relative thereto. The multi-mode vibration absorbing device is tuned such that it vibrates at the same frequency as the implement but out of phase therewith.
