“…The reason was that the average current density of the thick wire was too low, the initial stored energy was not effectively transferred to the wire. While the diameter of the wire was small, it exploded too fast, leaving a lot of energy on the pulse forming line [31,32]. When the discharge voltage was fixed at 5 kV, the wire length ranged from 10 mm to 20 mm, and the wire diameter ranged from 0.6 mm to 1 mm.…”

Electrohydraulic expansion joining has great potential for joining the light weight and high strength thin-walled pipes due to its high strain rate. Based on the central composite design (CCD) of response surface methodology, multiple experiments of electrohydraulic expansion joining process were performed. The multivariate quadratic nonlinear regression model between process parameters (discharge voltage, wire length, and wire diameter) and the ultimate pull-out load of the joints was established. The results revealed that discharge voltage, wire length and wire diameter all had a significant effect on the ultimate pull-out load. The discharge voltage had the most significant effect. The interaction between the discharge voltage and the wire diameter had a significant effect on the ultimate pull-out load. The optimal parameter combination (discharge voltage = 6 kV, wire length = 10 mm, wire diameter = 0.833 mm) was obtained and verified through the experiments. This study would provide guidance for the choice of the process parameters in real applications.

“…When the capacitor is charged to the voltage of 19.8 kV and the discharge load is a 50 mm length, 280 μm diameter copper wire, a pulsed current with the amplitude of 36.2 kA and a rise time of ~3.5 μs could be obtained. The resistive voltage can be obtained by subtracting the inductive voltage from the measured voltage, and specific calculating method can be found in references [ 23 , 27 ]. The recording digital oscilloscope adopts the discharge current as the trigger source, not the switch’s trigger signal, so the uncertainty of trigger process will not affect the measurement of the SW arrival times.…”

Underwater shock waves (SWs) generated by underwater electrical wire explosions (UEWEs) have been widely studied and applied. Precise measurement of this kind of SWs is important, but very difficult to accomplish due to their high peak pressure, steep rising edge and very short pulse width (on the order of tens of μs). This paper aims to analyze the signals obtained by two kinds of commercial piezoelectric pressure probes, and reconstruct the correct pressure waveform from the distorted one measured by the pressure probes. It is found that both PCB138 and Müller-plate probes can be used to measure the relative SW pressure value because of their good uniformities and linearities, but none of them can obtain precise SW waveforms. In order to approach to the real SW signal better, we propose a new multi-exponential pressure waveform model, which has considered the faster pressure decay at the early stage and the slower pressure decay in longer times. Based on this model and the energy conservation law, the pressure waveform obtained by the PCB138 probe has been reconstructed, and the reconstruction accuracy has been verified by the signals obtained by the Müller-plate probe. Reconstruction results show that the measured SW peak pressures are smaller than the real signal. The waveform reconstruction method is both reasonable and reliable.
