  • The detonation position and the shape of the explosive have a significant influence on the pressure of the underwater explosion shock wave, which makes it possible to use a small charge to form a shock wave that is equivalent to a large charge in a local direction. A charge design method to adjust the amplitude and duration of shock wave pressure was established based on the slender charge structure and parameter optimization design to carry out an underwater explosion shock resistance test of ship structure or equipment using a small charge. Firstly, based on the simple wave theory, the principle of shock wave pressure control and the objective function and constraint conditions of optimal design of charge parameters are given. Then, an independently developed software is used to study the energy of underwater explosion of slender charge, and the confidence degree of numerical simulation is verified through experiments. It is found that the influence of initiation position and charge shape on the pressure peak and duration of the underwater explosion shock wave is significant. The duration of shock wave pressure of slender charge column underwater explosion can be determined by geometric approximation. Finally, to further investigate the effectiveness of the proposed method, two charge schemes equivalent to the shock wave pressure of the prototype were designed and verified by numerical simulation. The prototype is taken from the pressure-time curve of the underwater explosion shock wave with TNT equivalent to 1000 kg and a stand-off of 100 m. The comparison results show that the designed charge can form a shock wave pressure-time curve equivalent to that of the prototype on the side of the initiation end within a predetermined duration. Since the bubble pulse is not considered, the established method applies only to the middle and far-field explosion shock problem.
