What is the characteristics of damped natural frequency?

The damped natural frequency is less than the undamped natural frequency, but for many practical cases the damping ratio is relatively small and hence the difference is negligible. Therefore, the damped and undamped description are often dropped when stating the natural frequency. For most structures the level of damping is such that the damped natural frequencies are very nearly equal to the undamped natural frequencies. Thus, if only the natural frequencies of the structure are required, damping can usually be neglected in the analysis. This is a significant simplification. Also, if the response of a structure at a frequency well away from a resonance is required, a similar simplification may be made in the analysis.

FAQ

What is Damped natural frequency?

Damped natural frequency is a frequency if a resonant mechanical structure is set in motion and left to its own devices, it will continue to oscillate at a particular frequency and is represented as ω_d=ω_n*sqrt(1-(ζ)^2) or Damped natural frequency=Natural frequency*sqrt(1-(Damping ratio)^2). Damping ratio is a dimensionless measure describing how oscillations in a system decay after a disturbance and Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force.
