In physical systems, damping is the loss of energy of an oscillating system by dissipation. Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. Examples of damping include viscous damping in a fluid (see viscous drag), surface friction, radiation, 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 suc

This paper presents an eddy current damper model that can store electrical energy. The damper is mainly used under strong impact load.
Energy damping is defined as the ability to absorb unwanted vibrations and noise generated by mechanical systems. Damping systems provide several advantages such as the improved lifetime of dynamic structures, compactness, short inspection time, and reduced noise pollution.
In physical systems, damping is the loss of energy of an oscillating system by dissipation. Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation.
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)). Damping is not to be confused with friction, which is a type of dissipative force acting on a system. Friction can cause or be a factor of damping.
From the physical point of view, there are many possible sources of damping. Nature has a tendency to always find a way to dissipate energy. All real materials will dissipate some energy when strained. You can think of it as a kind of internal friction.
Active damping is gained by controlling generated stress or strains of SMA in a reinforced hybrid composite material. By benefiting from the damping characteristics of SMA reinforcement (e.g. SMA wire), a structural element is used to absorb unwanted mechanical energy.
The energy is dissipated usually in the form of heat, which leads to a gradual reduction in the motion of the oscillating system. Examples of damping include: Depending on the system’s nature, damping can occur through various mechanisms, such as frictional forces, air resistance, or electrical resistance. 1. Viscous Damping
