Vibration analysis is a very broad term. At ETS, it refers to the characterization of the performance of a machine or structure and the provision of solutions to uncovered problems. Using state-of-the-art large scale diagnostic tools, ETS is able to determine cause and effect relationships which form the basis for recommended remediation. Measurements may be the short term capture of transients through run-up or coast-down or require long term recordings that capture unique events or trends. Projects may include determination of resonances, vibration isolation studies, equipment commissioning evaluation, warranty assessments, or failing machine component diagnosis. One unique example is the identification of the resonant frequency of a large shaft by taking several thousand linear averages over a several hour period in order to tease out the result.
