Fault Diagnosis Method of Rolling Bearing Based on Singular Value Decomposition
To determine the dimension of Hankel matrix and the number of singular values in singular value decomposition(SVD),a new method to determine the matrix dimension and the number of singu-lar values was proposed to achieve the fault diagnosis of rolling bearings.The proposed method was ap-plied to the measured fault signals of the inner and outer rings of the rolling bearings.Through denois-ing of the signals and envelope spectrum analysis,the useless frequency components in the measured vi-bration signals were effectively eliminated,and the fault characteristic frequencies contained in the sig-nals were extracted.
