Abstract

Abstract

For the "abnormal discharge" phenomenon of the pulse signal electric probe due to the micro-jetting, we proposed a K+R_x equivalent circuit model of the micro-jetting and conducted the explosive loading experiments to explain the discharging mechanism of the electric probe conducted by the micro-jetting. According to the X-ray testing data, the discharging position of the electric probe obtained was in the transition zone from the micro-jetting to the micro-spall, and the abnormal discharge phenomena of the electric probe were classified into three types. Thus we proposed a circuit simulation model where the micro-jetting is equivalent to a K+R_x circuit. By adjusting the parameters of the K+R_x equivalent circuit model, the three types of the "abnormal discharging" phenomena of the electric probe were simulated. The simulation results show that the K+R_x equivalent circuit model provides an excellent explanation for the discharging of the pulse signal electric probe conducted by the micro-jetting.
