Vibration & Spectrum Analysis
Vibration analysis is a process that monitors vibration levels and investigates the patterns in vibration signals. It is commonly conducted both as a vibration signal versus time directly, as well as on the frequency spectrum.
In real world applications of rotating machinery, it is highly desirable to incorporate the frequency spectrum analysis in addition to physical signal analysis.
A complex machine with multiple moving components will generate a mixture of vibrations, which is a combination of vibrations from each rotating component. Therefore, it is difficult to use only physical signals to examine the condition of the critical components such as wheels, bearings, and shafts in rotating equipment.
Frequency analysis decomposes the physical signal versus time and describes the repetitiveness of vibration patterns, so that the frequency components corresponding to each component can be investigated.
