Abstract
Vibration analysis of machines gains greatly in efficiency if periodic vibrations can be separated out from non-deterministic ones. Part II of this paper introduces a solution in the frequency domain, which is faster and simpler to use than adapative algorithms (part I). The performance of this new algorithm is thoroughly investigated and compared to those of the self-adaptive noise cancellation algorithm. Finally, convincing examples are given of the application to the separation of actual bearing signals from gear signals in gearboxes.
