Abstract

In order to study effects of wave-shaper on jetting projectile charge of sub-semisphere shaped charge, the AUTODYN-2D software was used to simulate formation of projectile. The results show that jet velocity and charge's energy transformation rate have been improved obviously with the wave-shaper. According to analysis on the effect of wave-shaper parameters diameter d and wave-shaper bottom from the liner top distance H of two factors on jet molding by orthogonal design method, the wave-shaper diameter d is the main influencing factor, and H should not too large. The impacts of five wave-shaper materials on jet formation including polyurethane, rubber, nylon, teflon and polystyrene were analyzed by comparison, it shows that the best material is nylon.
