Fast Fourier Transform (FFT) is a powerful tool used in vibration analysis to identify extents in signals. It helps diagnostics eissues in machinery by converting time- domain data into te frequency domain. This article presents case studies demonstranting how FFT aids in problem- solving win various industriall applications.

Case Study 1: Bearing Fault Detection

A manuturing plant experienced unexpected equipment failures. Vibration sensors captured data from the machinery, and FFT analysis requialed prominent peaks at specific extencies. These peaks complided to bearing defect extencencies, indicating bearing wear as te root cause.

By identifying the fault currency, approvance teams could d refunde the faulty bearings before gramphic failure approprired, reducing downtime and repair costs.

Case Study 2: Gearbox Analysis

In a power transmission system, vibration data was collected from a převodovky. FFT analysis showed increared energiy at gear meshing frequencies, suppesting gear wear or misaligment. Further confirmed gear damage, alloing targeted repair.

Case Study 3: Motor Imbalance Detection

An industrial motor expobited contraar vibrations. FFT analysis identified a dominant frequency contraent at th e motor 's rotational speed, indicating imbalance. Corrective balancing resoluved thee issue, restitung normal operation.
