The acoustic signal of gas pipeline leakage has advantage in short delay time and carries physical information of the leakage, so it can be used for the diagnosis and localization of the pipeline leakage. In the long distance pipeline, collecting vibration signal caused by sound field has important significance to research of acoustic leakage detection technology. In order to get sound signal, first, this paper researches on the phonation principle of the pipeline leakage and the characteristic of the sound source, and the sound field is established on the basis of aero acoustics. Second, the vibration of the pipeline wall is analyzed with the harmonic analysis technology of the ANSYS software when the leak wall bears broadband harmonic sound pressure. Finally, the field experiment demonstrates that this approach can improve detection ability of small leakage with low false alarm rate.
