Things To Know About Anti-Vibration Mounts

Anti-vibration mounts are a popular type of suspension for mechanical equipment, mainly because it is a cheap and effective way to reduce unwanted vibrations from equipment. It primarily acts as a structural support by reducing the amplitude of vibration from transmitted forces from one part transferring to another, or from external sources to the machine.

Anti-vibration mounts can be described as one or more springs that work against each other to reduce the amplitude and transmission of vibration through a machine. The anti-vibration mounts can also behave like a dashpot by dissipating energy, converting kinetic energy into heat.

A common example would be car shock absorbers, but there are many different types such as viscous, tuned mass dampers and elastomeric.

Anti-vibration mounts today are most commonly used in cars and aircraft for noise and vibration suppression. They can be found in almost all modern cars made since the 1960s to improve the comfort of passengers by reducing vibrations from the road surface, engine and exhaust system etc. By reducing the vibrations, it also reduces the noise that is emitted from the car.

Aircraft use anti-vibration mounts for a similar reason – to reduce cabin noise and vibration. The mounts are usually found in the engine and landing gear compartments, where they help to isolate the equipment from the rest of the aircraft. This improves passenger comfort and also helps to keep the aircraft’s weight down, as excessive vibrations can add unnecessary stress to aircraft components.

There are many different types of anti-vibration mounts, but the most common are those that use springs. The main benefit of using springs is that they are relatively cheap and easy to manufacture, and they can be tuned to meet the specific needs of a product.

Elastomeric anti-vibration mounts use rubber or similar materials in an enclosed housing to isolate a machine from vibration. They are used in applications where vibrations need to be reduced, but they cannot be tuned or need a low profile mount. The main drawback is that they lose their effectiveness at high frequencies, so they are not suitable for all applications.

Tuned mass dampers are used to reduce the vibrations of a machine that is resonating at its natural frequency. The damper consists of a mass attached to a spring, and when the mass moves, it absorbs the vibration energy.

This type of mount is often used in high-vibration applications, and they can be very effective in reducing the amplitude of vibration.

Viscous dampers are used to dissipate energy in a machine, and they work by using a fluid to dampen the vibrations. The fluid is usually a silicone oil, and the damper consists of two discs that are separated by the fluid.

When the discs rotate, the fluid creates a resistance to the rotation that dissipates energy and reduces vibrations. This type of mount is often used in applications where there is a lot of vibration, such as in heavy machinery.

Viscous dampers also dissipate energy, and they work by using a fluid to dampen the vibrations. Active mounts such as tuned mass dampers are used to reduce the vibrations of a machine that is resonating at its natural frequency.
