WebDamped vibration is described as the kind of vibration in which resistance force/friction force acts on the vibrating system. In this type of vibration, as the system oscillates, there is loss of energy with movement takes place, which means the system vibrates with decreasing frequency. The diminishing of vibrations with time is called damping. WebApr 11, 2024 · In damped vibrations, there is an external force which affects the free vibration, it dampens or reduces the amplitude of the system. When an external force is provided to show resistance to the motion of the system, hence ultimately stopping the motion of the system, then such vibrations are called damped vibrations. ...
