摘要: The invention discloses a fault diagnosis method for an anti-interference rotating machine. comprises the steps that data signal of machine is preprocessed; Meyer wavelet filter group adopted decomposing in step 1; multi-decoloring cycle harmonic rate value each sub-band decomposition tree 2 calculated; square envelope spectrum parsing sub-signal with largest diagram selected as result; if greater than times historical value, it diagnosed probability diagnostic object 80%. constructed to characterize band signal-to-noise ratio, used replacing spectral kurtosis index fast diagram; replace FIR diagram, and can solve leakage problem center analysis frequency packet.
