摘要
Abstract
In order to study the effect of liner configuration on the formation of jetting penetrator charge of hemispher-ical liners with variable thickness, three hemispherical liners with equal mass were designed, including equal-thick liner, center thicker liner and edge thicker liner. LS-DYNA software was used to simulate the formation and penetration of jetting penetrator charge. And the experiment of jet penetrating against target was carried out at long charge diameters standoff distances. Results show that liner configuration leads to the dissimilar way of rod like jet formation, and liner configuration has a significant influence on shape and velocity of jet. Jetting penetrator charge with the center thicker liner presents the best penetration performance, the equal thick liner follows, and the edge thicker liner is the worst.关键词
