Abstract

Abstract

When a charge explodes in water, differentwater pressure exerts different in fluences on the explosive parameters. Using the finite element analysis software ANSYS/LS-DYNA, a simulation model of a typical charge explosion under different water pressure is established. The blastwave pressure at different points under different water pressure is calculated, and the blastwave pressure changing with water pressure is analyzed. The basic law of the in fluence of water depth on blastwave pressure is concluded. This research will be valuab le to these fields, such as the assessment of warhead lethality of underwater weapons, and the design of fuze range, etc.
