Vibration Testing & Investigations

Vibration Testing & Investigations


Unexpected high levels of vibration are usually a result of large magnitudes of input forces or the excitation of a resonance. Many factors can influence the forces, such as bent shafts or out-of-balance masses in rotating machines, and there are numerous ways to investigate their source. If no excessive forces can be discovered, yet there is high vibration, then resonance must be suspected.

Noise & Vibration Measurement

Noise & Vibration Measurement


High noise and vibration levels can be a source of nuisance, affect health and well-being and be a cause of damage to buildings, structures and equipment. Eatec specialises in measuring levels of noise and vibration and assessing the results against national and international standards. Monitoring can be short or long term to suit the individual conditions of the environment.

Noise & Vibration Monitoring and Assessment on Construction Sites

Noise & Vibration Monitoring and Assessment on Construction Sites


Work on construction and demolition sites creates environmental noise and vibration that can be a nuisance to neighbouring properties. Guidelines in the Control of Pollution Act (1974) give levels that are considered to be acceptable, and local authorities under Section 60 are given powers to ensure that working practices are modified to comply with the limits. Producing an acceptable noise and vibration working plan under Section 61 for a building site will satisfy the local authority, providing that measured evidence shows compliance. This evidence comes from monitoring.

Noise & Vibration on Ships

Noise & Vibration on Ships


Ships are inevitably places of relatively high levels of noise and vibration. Crew are often required to work for long periods in an environment that could be harmful to health if the proper precautions are not taken. Vibration can result in premature failure of equipment where levels become excessive. Providing there is a good understanding of the sources of noise and vibration on ships and their transmission to working areas, it is usually possible to reduce the input levels or introduce sufficient attenuation to avoid health or equipment problems.

Shock and Impact Testing

Shock & Impact Testing


Shock and impact testing is used to confirm that structures are capable of withstanding extreme dynamic events which could occur in-service.
