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 and climate control - for example, in the case of Volume Control Dampers. [1] Its operation can be manual or automatic. Manual dampers are turned by a handle on the outside of a duct.
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.
An example of this concept being applied is the brakes on roller coasters. [16] Magnetorheological Dampers (MR Dampers) use Magnetorheological fluid, which changes viscosity when subjected to a magnetic field. In this case, Magnetorheological damping may be considered an interdisciplinary form of damping with both viscous and magnetic damping ...
An example of the latter is a crankshaft torsional damper. Mass dampers are frequently implemented with a frictional or hydraulic component that turns mechanical kinetic energy into heat, like an automotive shock absorber.
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
Damper (food), a bread of the Australian Outback; In mechanical engineering, a damper is a device for suppressing vibrations in a mechanical system by dissipating energy. Dashpot, a type of hydraulic or mechanical damper; Shock absorber (British or technical use: damper), a mechanical device designed to dissipate kinetic energy
Typical examples of viscous damping in mechanical systems include: Fluid films between surfaces; Fluid flow around a piston in a cylinder; Fluid flow through an orifice; Fluid flow within a journal bearing; Viscous damping also refers to damping devices. Most often they damp motion by providing a force or torque opposing motion proportional to ...
Coulomb damping is a type of constant mechanical damping in which the system's kinetic energy is absorbed via sliding friction (the friction generated by the relative motion of two surfaces that press against each other).
