Figure 16. Left: run-up of a nearly axisymmetric system. 5% asymmetry showing the amplification of the vibration at n 2 An effective fault detection procedure would use order tracking to extract the vibration amplitude at the appropriate frequency which is speed dependent and would thus combine the approaches of sections 1,2 and 3. (16)-right when the tuned parametric excitation matches the aforementioned condition. 5 SUMMARY This paper discussed signal processing methods geared specifically to rotating machines.
