Can someone explain me how are the different frequency bands useful for detecting bearing faults using resonance demodulation?

This presentation has a pretty good overview of characterizing bearing faults. In essence, once the measured frequency content does not match what is considered a good response from a bearing, it can be flagged as faulty or nearing fault.

  • $\begingroup$ Thanks for sharing this presentation. But it still doesn't answer my doubt. I need to know how to select the frequency bands in resonance demodulation. $\endgroup$ – user3217416 May 7 '14 at 5:47
