In this article, we will be looking at what the common faults that can be detected with vibration analysis. To begin with, it should be important to understand what vibration analysis is, the applications it is used in as well as to understand what faults can be detected.
Vibration analysis is a process which monitors the vibration levels and identifies trends or patterns in vibration signals. The waveforms are directly in sync with the vibration signal directly, specifically on the frequency spectrum.
The main source of identifying the common faults is through a Vibration Monitoring System which has predetermined parameters related to vibration level, recording intervals and frequency bandwidths.
Advantages associated with vibration analysis is Real-time reaction of structural conditions, supports remote condition monitoring as well as establishing signal analysis and algorithms for predictive maintenance.
When any abnormalities are evident, parameters such as standard deviation, skewness and other factors are identified. The applications in which vibration analysis is used are for rotating machinery that incorporates rotating components that decomposes waveforms and vibration patterns; in addition, the vibration can occur in different forms such as displacement, velocity and acceleration.
The vibration components are also directly correlated to meshing gear-teeth, rolling bearing elements, rotating electrical fields, fluid flows, combustion events and other structural rotations.
