Small Caliber Shaped Charge Research

Tank is still main weapon for the future ground war in air-ground, great depth and high mobility stereoscopic war that high technology is applied mainly. The defense and attack against tank is the one of the keys for the ground battle. Therefore, the all worldwide countries pay great attention to anti-armored weapon. In order to increase the anti-interference ability of tank, the many countries would lower the effects of AP (armor piercing) shell and HEAT (high explosive antitank) cartridge by use compound armor, reactive one and interval one that can resist HEAT cartridge very well.The text discusses from the shaped charge source and the structure of HEAT cartridge, the main factor of influencing it, and penetrating armor principle of inclined double-layer reactive armor, carries out the simulated analysis for the most advanced inclined double-layer reactive armor with break-break tandem warhead in its front-stage initiating. It simulates the conditions that LS-DYNA is relative to the different liner structures, the different wall thicknesses and the different cone angles for the same liner, and adopts the Beijing science and engineering university's Held evidence for the inclined double-layer reactive armor to distinguish, makes the verification for the reliability of the simulation with the trial method finally.
