Abstract

Detecting leakage liquid-filled pipe by acoustic emission instrument and researching the acoustic signal that measured with water by experimental medium. Gathering the acoustic signals in different pressures or different diameters of leakage aperture and analyzing the spectrum characteristics by wavelet packets and db5 wavelet basis. The result show that major frequency components contained at about 232KHz-239KHz. The acoustic emission signals’ amplitude and energy enhance as pressure and leakage aperture diameters’ increase.
