| Abstract: | Begin with Fourier analysis and fisltration,the wavelet transform and p roperties are discussed from the angle of enginering in the pa per.Through vibration signal of lar ge bearing is Time -frequency analysed using wavelet band -psaain g methods,the type,the position adn degree of large bearing are con-firmed.The post -disassembled fits the diagnosis well. |
