| Abstract: | In this paper, Wavelet Analysis Method (WAM) is introduced to analyse the non_stationary, shock signals. The theory and construction method of wavelet, the fast algorithms of wavelet analysis are presented. As an example, the gear testing signal has be analysed by WAM, and the results of WAM are compared with that of Fourier spectrum. The advantages of WAM are clearly shown. |
