Abstract: A new method on identifying the dynamic characteristics of bearings is presented. The identifying model has been set up. In the processing of vibration signal, the wavelet transform is used. The experiment results show that this method can decrease the influence of measurement error on identifying precision and improve the precision of identification.

Key words: Identification, Journal bearings, Least-square method, Wavelet transform
