概要

Abstract : Structural faults are often occurring in a rotating machine, such as, u nbalance, misalignment and looseness etc., and their feature spectra of vibration signal appear in the low frequency area. The precise diagnosis for the structural faults type is difficult in the real plant, because of the noise in the vibratio n signal and the complex structure of the plant machine. In this study, we propose d the precise diagnosis method of structural fault for rotating machinery using en veloped wave spectra, signal fusion and LSM (Least-squares mapping principal compo nent analysis. The method proposed here has been verified by practical diagnosis.
