Vibration Isolation Mount
A precise tool.
What is the Vibration Isolation Mount & How does it work?
Vibration isolation mounts are used to decouple equipment from supporting structures, reducing the transmission of harmful vibrations that can cause premature wear, noise, or failure.
The key parameter governing isolation performance is the mountβs natural frequency (f_n). When the excitation frequency is well above f_n, the mount provides significant attenuation.
To select an appropriate mount, engineers compare the equipmentβs dominant vibration frequency with the calculated f_n. A common rule of thumb is to keep the natural frequency at least oneβthird of the excitation frequency.
f_n = frac{1}{2pi}sqrt{frac{k}{m}}
f_n = natural frequency (Hz)

Frequently Asked Questions
What is the purpose of a vibration isolation mount?
A vibration isolation mount is used to decouple equipment from its supporting structure, reducing harmful vibrations that can cause wear, noise, or failure.
How do you calculate the natural frequency (f_n) of a vibration isolation mount?
The natural frequency (f_n) is calculated using the formula f_n = 1/(2Ο)β(k/m), where k is the spring constant and m is the mass.
When should I use a vibration isolation mount?
You should use a vibration isolation mount when you need to reduce vibrations that could cause premature wear, noise, or failure in equipment.
What happens if the excitation frequency is below the natural frequency of the mount?
If the excitation frequency is below the natural frequency, the mount provides less attenuation and may not effectively isolate vibrations.
How do I select an appropriate vibration isolation mount for my equipment?
To select an appropriate mount, compare the equipment’s operating frequency with the mount’s natural frequency to ensure effective vibration isolation.
