A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
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 ...
Intumescent dampers swell shut due to intumescence in the event of a fire. Unlike mechanical dampers, it is a physical/chemical reaction that causes closure. Cleaning and an age assessment are periodically performed. The annulus of an intumescent damper is closed eliminating smoke migration. Also, intumescent fire dampers can be qualified to ...
A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and ...
The yaw damper is typically disengaged at ground level and turned on shortly after takeoff; an active yaw damper during the takeoff run could potentially mask serious issues such as engine failure. [ 2 ] [ 1 ] Equally, the system is commonly disengaged prior to landing, as it could inhibit the control authority to the pilot at the critical ...
A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used ...
