Abstract
According to the theory of dynamic test, this paper presents a DH5960-based dynamic signal analysis system, in which a diameter of 1422mm full-size high-pressure gas pipeline explosion experiments are performed. Air blast each measuring point P (t) curve is obtained, after the wavelet de-noising, the least squares method is adopted to carry out numerical fitting of the peak overpressure shock wave propagation characteristics in space. Decay curves and attenuation formula is obtained. Shock curve comparison between experimental group and the control group are done to discover the feature that high-pressure pipeline physics explosion air shock has a noncircular wave front propagation characteristics on the free-field near the ground.
