In this paper, experimental and numerical analysis on leakage through the heater inner tube, inner tube, with the study of leakage pressure leakage aperture size, propagation distance and the outer tube of liquid acoustic emission signal of the status and characteristics of acoustic emission signals of the mapping relationship, through the change of the above four factors, the leakage fault diagnosis...
This paper mainly studies the principle and key technology of acoustic emission signal wavelet denoising method, and conducted a comparative analysis on three kinds of wavelet denoising algorithm, while the wavelet function, threshold method in the three types of denoising comparison experiment, make analysis and reconstruction of lifting small wave denoising algorithm, using least square method,...
