摘要： In this paper, Wavelet Analysis Method (WAM) is introduted ic analysethe nonstationary, shock signals. The theory and construtction method of wavelet,the fast algorithms of wavelet analysis are presented.As an example,the gear testing signalhas been analysed by WAM.and the restults of WAM are compaed with that of Fourier spectrum.The advantaes of WAM are clearly shown.
