Abstract

A new explosive reactive armor based on the structure of annular shaped charge is designed to further improve the protective performance of explosive reactive armor and the survivability of tanks on the battlefield, which is used to intercept the high speed and large length-to-diameter ratio rod penetrators. The process of annular explosively formed projectile (EFP) interfering on the rod penetrators isnumerically simulated using the finite element software ANSYS/LS-DYNA, and both the process of annular EFP forming and the mechanism of interfering on the armor piercing projectile are analyzed. Under the same conditions, the processes of interfering on the rod penetrators by linear and annular EFPs are compared. The results shows that EFP with annular shaped charge has the higher defense performance. The effective penetration depth of long rod projectile is reduced by 32.5% compared to EFP with linear shaped charge, and the length of crater is increased by 10.4%. The long rod projectile is broken and yaws under the interference of annular EFP. The simulated results are in good agreement with the test results. Key
