Damping
Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators. Damping not based on energy loss can be important in other oscillating systems such as those that occur in biological systems and bikes (ex. Suspension (mechanics)). Not to be confused with friction, which is a dissipative force acting on a system. Friction can cause or be a factor of damping. The damping ratio is a dimensionless measure describing how oscillations in a system decay after a disturbance. Many systems exhibit oscillatory behavior when they are disturbed from their position of stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Damping (music)
Damping is a technique in music for altering the sound of a musical instrument by reducing oscillations or vibrations. Damping methods are used for a number of instruments. Strings Damping is often necessary on string instruments such as the bass or violin where sympathetic resonance can excite other strings creating undesired noise. This phenomenon can be remedied by keeping fingers such as the thumb on the strings where the vibration is unwanted. On guitar, damping (also referred to as choking) is a technique where, shortly after playing the strings, the sound is reduced by pressing the right hand palm against the strings, right hand damping (including palm muting), or relaxing the left hand fingers' pressure on the strings, left hand damping (or left-hand muting). Scratching is where the strings are played while damped, i.e., the strings are damped before playing. The term presumably refers to the clunky sound produced. In funk music this is often done over a sixteenth note p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damping Torque
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. Damping torque or damping forces is the speed deviation of an electromechanical torque deviations of a machine while the angle deviation is called synchronizing torque In a measuring instrument, the damping torque is necessary to bring the moving system to rest to indicate steady reflection in a reasonable short time. It exists only as long as the pointer is in motion. Under the absence of damping torque the pointer oscillates for a short period of time and comes to steady position and this situation is called under damping. If the damping force is too large, then the pointer will come to rest slowly and this is called as over damping. Damping torque is a ph ...

Damping Capacitor
Film capacitors, plastic film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes. The dielectric films, depending on the desired dielectric strength, are drawn in a special process to an extremely thin thickness, and are then provided with electrodes. The electrodes of film capacitors may be metallized aluminum or zinc applied directly to the surface of the plastic film, or a separate metallic foil. Two of these conductive layers are wound into a cylinder shaped winding, usually flattened to reduce mounting space requirements on a printed circuit board, or layered as multiple single layers stacked together, to form a capacitor body. Film capacitors, together with ceramic capacitors and electrolytic capacitors, are the most common capacitor types for use in electr ...

Damping Matrix
In applied mathematics, a damping matrix is a matrix corresponding to any of certain systems of linear ordinary differential equations. A damping matrix is defined as follows. If the system has ''n'' degrees of freedom ''u''''n'' and is under application of ''m'' damping Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation.
