Abstract

Abstract: In order to obtain an equivalent underwater explosion impulsive loading, the theoretical analysis is carried out for the impact of a flyer plate on a piston, which seals a conical target chamber filled with water, based on one-dimensional elastic wave propagation and a linear equation of state for water. The impact process is simulated by using AUTODYN software, and the decay times of shock waves for two pistons with different thicknesses are analyzed and compared. According to the theory and numerical simulation research, an equivalent equipment is designed, and the pressure-time curve is measured at the central point of chamber medial wall. The results show that it is feasible to obtain an equivalent underwater explosion shock waves in the laboratory through high speed impact, and the flyer speed and the piston thickness determine the peak pressure and decay time in the conical target chamber, respectively. The equivalent equipment can be used to investigate the shock response of typical structures and materials subjected to underwater explosion impulse loading.

Key words: explosion mechanics, underwater explosion, target chamber, impact, shock wave loading
