4 Steps To Choosing The Right Anti Vibration Mount
In machinery, noise and vibrations can be a pertinent problem. Constant vibration can eventually lead to the weakening of machinery parts or structural damage in buildings, not to mention noise pollution. For the machine, this would also lead to a more frequent need for repairs and replacements, accumulating unnecessary costs for the company.
To counter this, anti vibration mounts are often used as a key part of reducing the transfer of vibrations from machines. By absorbing the impact of the movements, machinery can operate more quietly and stably. In fact, these mounts, often made from a flexible material like rubber, have found uses in a range of industries, including in power generation and the defence sector.
Anti vibration mounts might just be the answer to your machinery’s noise or vibration problem. But how should you choose the right anti vibration mount? Not to worry, let our guide help you get started!
1. Determine the weight of mounts you need
Mounts are categorised according to the weight they can support. To choose the right weight for your mount, you need to know the total weight of your equipment and the number of mountings you will be using. Usually, you can divide up the total weight of your machine by the number of mountings to be used.
However, consider that the weight of your machine may not be evenly distributed. In that case, you may need to use different types of mounts at different parts of the machine.
2. Find out the running speed of your machinery
You’ll need to know the machine’s normal running speed, also known as the forcing frequency. This is typically measured in repetitions per minute (RPM) and is an indication of how much the machine vibrates when it is in operation.
3. Calculate the required static deflection
Deflection refers to how much the mount will compress under the weight of the machine. For example, if a 10cm mount compresses to 9.5cm under a piece of equipment, the static deflection is said to be 5mm. You can calculate the amount of deflection you need using the rpm of your machine and the targeted degree of isolation you wish to achieve.

4. Choose the correct type and number of mounts
With the above information, you should have a good idea of what type of anti vibration mounts you should be looking for. Some other things you may also want to consider are the material of the mounts you select. While the material can affect core properties like the amount of deflection and natural frequency of the mounts, you also want to ensure the material is suitable for its application.
For example, you may need to take into account the ability of the mount’s material to withstand high temperatures or in resisting corrosion from certain chemicals. Some of the anti vibration mounts on the market include rubber vibration mounts and TPE vibration mounts.
Conclusion
Recognising the importance of anti vibration mounts is the first step in prolonging the lifespan of your machinery and reducing the effects of noise pollution and the risk of structural damage. We hope this guide gives you a good idea of which anti vibration mounts you should go for. If not, we are most happy to offer our assistance in recommending the best type for your machinery’s needs.
