Vibration Absorbers

Proven to reduce resonant vibration

In conjunction with the Gas Machinery Research Council, Wood (BETA Machinery Analysis) has developed the damped vibration absorber (DVA).

This rugged absorber is ideal for existing compressors, pumps or piping systems experiencing high vibration due to resonance. It can also be installed at the design and construction stage to avoid a known resonance problem.

The damped vibration absorber (DVA) can be applied to vessels, piping, and other locations that are resonant.  For reciprocating compressor packages, a common application is near the top of resonant scrubbers or piping near coolers or PSVs. 

As the name implies, the DVA absorbs vibration using a tuned mass/spring configuration. The unit won’t fail from excessive vibration, nor will it need any maintenance. It can be installed “hot,” an important advantage for many operators. 

The DVA is mounted in place:

  • With a band clamp (supplied as standard)
  • Attached to mounting tabs on equipment
  • By a magnetic mount for temporary testing applications

How it Works

Although new to the market, the vibration absorber is based on well-known physics. It has been developed in conjunction with a reputable partner (GMRC) and has been built, tested and proven to work.

At resonance, the DVA will cut vibration to lower levels. In many cases, the vibration amplitudes are reduced by 50%. The goal of the device is to reduce vibration to acceptable levels – not entirely eliminate vibration.

The unique feature behind the DVA is that it has an extremely long life and will not fail due to excessive vibration. The design has no stress concentrations; this ensures a reliable, long-lasting solution to heavy-duty industrial applications.

The effectiveness of the vibration absorber has been proven in extensive tests

The vibration absorber unit is tuned to the target frequency – to achieve maximum performance.

By comparison to other vibration solutions, the total cost of applying the DVA is small. No modifications are needed to the piping, vessel, or skid. No supports are required. The unit can be installed quickly in minutes, with no special tools or equipment.
