A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] 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 ...
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. [1] Compared to modern shock absorbers friction dampers only provided limited shock absorption but served mainly to damp down oscillation.

Damper (flow) Opposed blade dampers in a mixing duct. A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...
In July 1978, a possible structural flaw was discovered in Citicorp Center, a skyscraper that had recently been completed in New York City. Workers quietly made repairs over the next few months. The building, now known as Citigroup Center, occupied an entire block and was to be the headquarters of Citibank. Its structure, designed by William ...
Blast damper. A blast damper is used to protect occupants and equipment of a structure against overpressures resultant of an explosion. The blast dampers normally protect air inlets and exhaust penetrations in an otherwise hardened structure. Blast dampers are related or identical to blast valves, the latter name is generally used to describe ...
A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [1][2][3] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.
A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [1] The resulting force is proportional to the velocity, but acts in the opposite direction, [2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram ...
