Understanding Vibration Analysis




Vibration analysis tend to involve looking for any anomalies from any given vibration system. Any object in motion tends to have a vibration but tends to come with frequency, intensity, and amplitude. The vibration in an equipment can be used in the measurement of the equipment in question. Through vibration analysis, it would be possible to find a developing problem in a given equipment and hence move fast to repair the machine increasing its lifetime. A vibration analysis tend to also be used to detect as well as monitor problems that when not repaired only get worse with time. The vibration analysis is also used to test whether the installation or repair has been properly conducted. Vibration monitoring is also used as a predictive tool of the maintenance program of the equipment in question.


There are so many techniques that tend to be used as vibration measurement techniques. However, most of them tend to present a waveform over time. They tend to present an amplitude as a function of frequency or the amplitude as a function of time. The vibration spectrum can also be established from any rotating equipment and its behavior can be monitored with the intention of optimizing its functionality.


Vibration analysis also tends to involve a time waveform analysis which is not necessarily a primary tool but a tool used to ensure additional insight. In a case where one is dealing with a low-speed application, a time waveform analysis could be used as it tends to reveal how the equipment is moving. In a case where one is dealing with gears, a time waveform tends to be the best analysis.



The phase analysis may also be used especially when there is some trigger. A phase analysis is used in a case where there is any vibration that may be introduced by anything that has to do with the rotation of the shaft frequency. One of such could be bearing defects and phase analysis is used in determining where the vibration occurs on the shaft.


Vibration data analysis may also be evaluated in terms of synchronous, asynchronous, and subsynchronous features. One would also be amazed to know that there are online vibration monitoring services with the intention of optimizing the maintenance and performance of industrial assets. It is essential to note that even while the manual readings can be captured over time giving useful information, the machines on the other end tend to evolve continuously. For online vibration monitoring, it would be essential for one to ensure smart components which include wireless connectivity. That way, one would be sure that the online vibration and condition monitoring system would be possible. One would also need to ensure technical maintenance, motor balancing and vibration balancing with the intention of optimizing the performance of the equipment.
