Vibration Isolation Calculator
The Vibration Isolation Calculator finds the natural frequency, frequency ratio, and resonance margin for a machine on isolators. Example: for a 500 kg machine at 1500 rpm on spring isolators, Natural frequency = 3.18 Hz, Frequency ratio = 7.85, Resonance margin = 685.4 % (per ISO 10816-3 | ISO 20816-1 | ISO 21940-11 | ANSI S2.19 | Rao Mechanical Vibrations 6th Ed.).

How to use this calculator
- Enter the figures for the duty you are sizing: the worked example below uses a 500 kg machine at 1500 rpm on spring isolators.
- The calculator returns Natural frequency, Frequency ratio, Resonance margin, computed per ISO 10816-3.
- Check the worked example to confirm the method matches how you would do it by hand, then run your own numbers in the interactive tool.
FAQ
What is a vibration isolation natural frequency calculator?
The Vibration Isolation Calculator is a free online tool that computes finds the natural frequency, frequency ratio, and resonance margin for a machine on isolators. It shows the formula and a fully worked example so you can check the method, not just the number.
How is it calculated?
The result is computed from your inputs following ISO 10816-3. The worked example on this page shows a real computation with real numbers.
Is the calculator free?
Yes. WorkHive's engineering calculators are free to use, no sign-up needed for the tools. WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
