A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, long cantilevered signs and cable-stayed bridges. The dumbbell-shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main cable. The ...
Stockbridge dampers Stockbridge damper bolted to line close to the point of attachment to the tower. It prevents mechanical vibration building up in the line. Stockbridge dampers are added to the transmission lines a meter or two from the tower. They consist of a short length of cable clamped in place parallel to the line itself and weighted at ...

Stockbridge damper - absorbs resonant wave motions in wire and support cables, seen on high voltage power lines. [2] Shock absorber - motion redirected as heating of viscous oil forced through a restrictive passage [3] Inerter (mechanical networks) A mechanical analog to an electrical capacitor. [4]
Tuned mass damper inside bridge deck of the Jan Linzelviaduct. The tuned mass damper is widely being used as a method to add damping to bridges. One use-case for tuned mass dampers in bridges is to prevent large vibrations due to resonance with pedestrian loads.
Steering damper. Originally designed in 1966 by Leonard R Jordan Jr, [citation needed] the steering damper or steering stabiliser is a damping device designed to inhibit an undesirable, uncontrolled movement or oscillation of a vehicle steering mechanism, a phenomenon known in motorcycling as the death wobble.
Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war. Compared to modern shock absorbers friction dampers only provided limited shock absorption but served mainly to damp down oscillation.
The triangulation this offers is an attempt to reduce vibration, as is the use of Stockbridge dampers on the cables. The bridge is 5,240 ft (1,600 m) long, consisting of a 3,240 ft (988 m) central span between the towers and the two 1,000 ft (305 m) side spans.

Damping torque is provided by indicating instrument. Damper is a generic term used to identify any mechanism used for vibration energy absorption, the shaft vibration suppression, soft start and overload protection device. In order to design an efficient damper, it is imperative that the damping torque is calculated first.
