Abstract

Characteristics of electrohydraulic shockwave are the keys to the application of electrohydraulic disintegration of rocks (EHDR). Mathematical models are used to characterize the generation and propagation of the shockwave, an integrated experimental platform is established, the measured and simulated results of typical shockwave characteristics are analyzed. The simulated results of characteristics of shockwaves under different charge voltage are given, and the influence of charge voltage on the shockwave characteristics are analyzed. The results show that the peak pressure and energy of shockwave is 2.67 MPa and 27.30 J respectively, the wave front time is 2.16 μs, the loading rate is 1.24 MPa/μs, when the charge voltage is 11 kV. The peak value and energy of shockwaves increase, the wave front time decreases, the loading rate of shockwaves increases, while the efficiency of electrical energy transfer into shockwave energy decreases, when the charge voltage of capacitor rises. Characteristics of shockwaves can be predicted from the parameters of discharge circuit via simulation, thus to provide theoretical basis for further study on the morphology and effect of EHDR.
