Spectrum Analysis - SKF
A vibration FFT (Fast Fourier Transform) spectrum is an incredibly useful tool for machinery vibration analysis. If a machinery problem exists, FFT spectra provide information to help determine the source and cause of the problem and, with trending, how long until the pr oblem becomes critical.

Vibration - Wikipedia
The vibration spectrum provides important frequency information that can pinpoint the faulty component. The fundamentals of vibration analysis can be understood by studying the simple Mass-spring-damper model. Indeed, even a complex structure such as an automobile body can be modeled as a "summation" of simple mass–spring–damper models.

VIBRATION waveform as shown in the time drawing on the left side. This is the summation of all the vibration present at that location. Spectrum analysis enables us to untangle this complex waveform and make a representation of its original components on a diagram showing frequency on the X-axis and amplitude vertically.
Laser Alignment / Vibration Analysis | spectrum-ndt
Vibration analysis should be performed as part of a preventative maintenance scheme in order to reduce the possibility of unexpected failures or down time. Typically, VA is applied to rotating equipment such as shafts, pumps, motors, gearboxes etc. Conditions such as unbalance, misalignment, resonance or rolling element bearing faults can be detected assisting in remedial action.
