    Abstract

    Through an earlier experimental study, an integrated fault classification approach was suggested for machines operating at different speeds. The suggested method was observed to separate faults adequately, which can lead to fault diagnosis. However, theoretical understanding of the proposed methods is important to further enhance the confidence of the earlier experimental study. Hence, simplified mathematical simulations of different rotor faults are carried out and used to test the earlier proposed classification technique in this paper. Observations in the orbit, spectra and fault classification diagrams are consistent with the previous experimental case.
