VIBRATION ANALYSIS IN DOHA QATAR

Vibration Analysis Description: Vibration Analysis: Where to Start? VIBRATION ANALYSIS is a useful way to monitor machine health. Many plants have implemented regular vibration analysis plans to ensure the condition of their machines is being checked at regular intervals and so, if an issue comes to light after spectral analysis, a solution can be pursued.When analyzing vibration, it is important to be familiar with several terms. These are:FrequencyDisplacementVelocityAmplitudeThese are all terms that are used in vibration analysis on a spectrum. For example, the dominant frequency shown on a spectrum after data has been collected from the rotating machine will determine what kind of fault the machine is experiencing. This fault could be unbalance, misalignment, looseness, bearing failure, or a mix of two or more of these.The vibrations emitted from a machine are generally comprised of the primary frequency of a machine, which can usually be found at the rotating speed of the machine, as well as its harmonics and other sources within the machine. All of these vibrations add up to form a spectrum, which is a wide range of signals that need to be analyzed either by a vibration analysis software like Accurex and/or by a vibration analysis expert.Sometimes, whena forcing frequency coincides with a system natural frequency, resonance will occur. Engineers normally try to design around resonances because they can cause a dramatic amplitude increase which could result in premature or catastrophic failure of the s... View Full Blog Content...
