Does Damping Change Natural Frequency?

Damping refers to the reduction in oscillation magnitude because of the dissipation of energy. So to take it one step further, damping not only affects the gradual fading of oscillation amplitude, but it also affects the natural frequency of the oscillator. ... ​Damping decreases the natural frequency from its ideal value.

Does damping have an effect on natural frequency?

An analysis is presented of the effect of weak damping on the natural frequencies of linear dynamic systems. It is shown that the highest natural frequency is always decreased by damping, but the lower natural frequencies may either increase or decrease, depending on the form of the damping matrix.

Does damping change resonance frequency?

Increasing the damping will reduce the size (amplitude) of the oscillations at resonance, but the amount of damping has next to no effect at all on the frequency of resonance. Damping also has an effect on the sharpness of a resonance.
