As experienced vibration consultants - why you should speak to us first!
We are vibration consultants and here are reasons why you should approach us:
we have over 25 years' experience in vibration consultancy across various industries
we are chartered engineers in both mechanical engineering and acoustics
with specific reference to vibration engineering,
we instrument structures, machinery and equipment with accelerometers and strain gauges
we investigate fatigue and vibration related failures
we record vibration data
we analyse data
we update numerical models to recorded vibration and strain data
we design products and machinery to operate in vibration environments
and improve them to operate reliably and resiliently in its surrounding environment
we vibration test and develop products
All these reasons for using us as your vibration consultant, is backed by extensive experience and expertise. Every project that we have completed, was a challenge, and we provided the solution.
Why do we focus on vibration?
Here are a few key facts about our vibration consulting experience and why we chose to specialise in vibration:
Vibration is the source of noise and sound, and is the origin for the study of structural dynamics.
Vibration control suppresses unwanted vibration, structural behaviour, noise and sound.
Vibration is linked to all the above and acoustics, especially in the field of vibro-acoustics and building acoustics
These are the main reasons why we focus of vibration measurements and control. Throughout this website, you will appreciate that everything we do, will relate to vibration in some shape or form.
Vibration measurements, assessments and surveys
Vibration is usually measured with an accelerometer, which measures physical acceleration at its location. It is recorded and analysed with an FFT (Fast Fourier Transform) analyser, which converts the oscillations from the time domain to the frequency domain.
From this measurement and analysis, the magnitude and the frequency of the vibration is now known at the accelerometer location.
The magnitude of vibration only is usually used for assessments of levels to which people and structures are exposed. And is typically used as exposure limits, i.e. human vibration exposure, or building vibration levels etc. These are typically accompanied by time durations to which the person can be exposed.
We perform vibration assessments and surveys like these above, on buildings, large structures, machinery and equipment.
Assessing the environment
When the intensity is unknown, our vibration consultants assess the environment through measurements.
The measurement data collection process is intrusive. As we will instrument the structure or environment to determine the frequency content and levels thereof. We'll consider the corresponding frequency range to understand the noise implications, and process the data.
Analysis of this data will support our decision of any mitigation actions required
Vibration Testing
We have been involved in vibration testing since 1996. Our primary involvement is in
We've gained much knowledge in vibration testing. Therefore, we have included several case studies and lessons learnt on the vibration blog page of this website.
Often, our vibration consutlants get involved with a customer when a product does not pass a test. This usually increases the cost of the project.
We therfore urge you to get us involved in your project as soon as possible, so that we can steer you in cost efficiently.
We have overseen certification testing in several industries. We have seen conformity and failures. From the latter, we have found the reasons, and urge you once again to get us involved as soon as possible.
Mechanical Engineers and vibration consultants that ensure your product passes vibration testing
For many years we have conducted vibration testing of products. Many products failed on test for a variety of reasons.
This experience has given us expertise in designing products for the vibration environment. This knowledge and experience is what our vibration consultants provide you.
So, are you performing vibration testing on a product? Is it failing on a test? Are you concerned about the cost of continuing testing, and hping for success? Then give us a call on 01908 643 433 for help.
Vibration Analysis of Rotating Machines
Why we focus on rotating vibration?
The unbalance of the rotor in rotating equipment causes vibration throughout the unit.
Definition of unbalance on a rotor
Unbalance of a rotor will occur when a rotor or a component mounted on a rotor has a mass centre (or centre of gravity, i.e. COG) that is not coincident with the axis of rotation
Unbalance of a rotor is when the centre of gravity of the rotor does not coincide with the axis of rotation. Thus causes an off-balance.
The unbalance force and frequency dependents on the rotational eccentric mass and speed.
To balance a rotor to have no eccentric mass is impossible. But striving for the most perfect balance for a rotor is direct proportional to the cost of doing so.
This is why vibration isolation is necessary; to stop the vibration transmitting elsewhere. And to isolate any surfaces from vibration, consequently to mitigate noise radiation.
We are more than just vibration consultants
Our vibration consultants' experience is extensive, andmade us more than capable to work with other engineering disciplines. We understand the frustrations and challenges that other engineers face, and have helped any companies succeed.
You'll always get more than just vibration consultants from Environmentally Sound Limited.
We are mechanical engineers in product design and failure investigation, acoustics consultants and vibration consultants. Our service is what you want.
