Vibration Isolation Calculator
Static · formula-only · worked example computed when this page was built · no live data
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 it works
Computed from your inputs per ISO 10816-3 | ISO 20816-1 | ISO 21940-11 | ANSI S2.19 | Rao Mechanical Vibrations 6th Ed. Anything the worked example does not state uses this calculator's standard default; the interactive version shows every input and lets you change it.
Worked example (Mechanical & Machine Design)

How to use this calculator
- Read the worked example. It uses a 500 kg machine at 1500 rpm on spring isolators and shows every number in the method.
- Follow the formula with your own figures: it returns Natural frequency, Frequency ratio, Resonance margin, computed per ISO 10816-3.
- To compute interactively, open the Vibration Isolation Calculator inside WorkHive's free Engineering Design suite (link below). It runs the same method with your inputs.
FAQ
What is a vibration isolation natural frequency calculator?
The Vibration Isolation Calculator is a free online tool that 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 is free: this worked example is open to everyone, and the interactive calculator runs inside the free Engineering Design suite after a free sign-up (your work is saved to your account). WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
Run it on your own numbers
