Finite Element Simulation of Water Shock Tube Used for Dynamic Calibration of Underwater Shock Wave Pressure Sensor

By the known shock wave pressure curve, the shock wave of the underwater explosion was simulated loading on a specific target, the stress of the surface of the target, pressure value changes at a point as well as the characteristics response of the target. Through the simulation on the role of near-field characteristics of underwater shock wave acting on the target plate, this paper presents a new way to study the underwater explosion. We can get the pathway graph and its corresponding target corresponding renderings through this method. And all these results can guide the synthesis of new explosive formulations and new substances in the underwater explosives research.

Processing Circuit

A cheap signal processing circuit was designed to replace expensive special charge amplifier which was used for shock wave pressure sensor. We used conventional electrical components to design the charge amplifying circuit and the filter circuit. A fine image of shock pressure wave was got using this signal processing circuit in a real fire experiment.

Point Velocity

Detonating code is a flexible code with an explosive core. It is used to transmit the ignition of explosives with high detonation velocity in the range of 5.5 to 7 km/s. However, it is difficult to use detonating code for the explosive welding of common metals since the horizontal point velocity usually exceeds the sound velocity. Hence, in the present work, a new method using underwater shock wave generated by the detonation of detonating code was tried. The details of the experimental parameters and the results are presented. From the results it is observed that the above technique is suitable to weld thin metal plates with relatively less explosives.
