Abstract
A series of experiment and simulation were carried out to explore the peak pressure distribution in the near field of the cylindrical charge underwater explosion in the two cases of nine-point off-center detonation and central detonation. The shock wave peak pressures in the above two cases were obtained at the tested points with the distances and angles. And the directed peak pressure gain field was acquired in the case of nine-point off-center detonation. The results show that in the range of 750 mm and the angle of 0°~90° of underwater explosion field for the five-kilogram UHL-5 charge, the shock wave peak pressure by nine-point off-center detonation is higher than by central detonation.
