Ideal Damped Oscillation Frequency
Use this ideal damped oscillation frequency tool when you have measured values for natural hz, damping ratio. It applies a transparent mathematical relationship to those values to return an answer in Hz. Unlike a prediction or recommendation, this is a calculation from your inputs. Underdamped linear oscillator approximation only. Enter a different scenario to see how this particular quantity changes; check the assumptions before using it in a project.
How to use this calculator
- Use exact measurements and consistent units for natural hz, damping ratio.
- Enter each quantity; blank, nonnumeric and out-of-range inputs are not accepted.
- Compare the reported Hz quantity against your own data and the limitations below.
Formula for Ideal Damped Oscillation Frequency
Hz = natural_hz*sqrt(1-damping_ratio*damping_ratio). Inputs are expressed in the units shown by the labels.
- This uses a direct mechanics relationship and does not retrieve remote data, forecasts or individual account information.
- Underdamped linear oscillator approximation only.
Worked examples
Worked example — Ideal Damped Oscillation Frequency
Enter Natural hz = 10, Damping ratio = 0.18.
Apply natural_hz*sqrt(1-damping_ratio*damping_ratio).
Calculated value: approximately 9.836666 Hz.
Understanding the result
The example produces about 9.836666 Hz; this is a mathematical output for the example inputs, not an observed result for your project.
Underdamped linear oscillator approximation only.
Important notes
Underdamped linear oscillator approximation only.
Use values from the same measurement period or physical system. The result is in Hz and is not a guarantee of capacity, safety, ranking or revenue.
