In view of how the active material projectiles can be applied more effectively to the production projectiles to improve the power of the dynamic energy projectiles, a study was carried out on how the active material projectiles matched the target plate under different initial conditions. Autodyn-3D, a nonlinear dynamics numerical simulation software, was used to simulate the action behavior of the projectile. Based on the numerical simulation results of the invasion of 5 mm,20 mm and 35 mm RHA target plates by multi-group active material projectiles, the damage status of the projectile target, the stress distribution law of the projectile core and the change law of axial residual velocity were analyzed under different target conditions. The study found that when the 5 mm RHA target plate is invaded, the residual impact performance of the projectile is better but the internal stress value is low, which is not conducive to the occurrence of explosive action, and when the 20 mm and 35 mm RHA target plate is invaded, the pellet intrusion ability is not good at small caliber, but its axial residual speed and internal stress peak increase significantly and the impact of the target thickness on the internal stress peak will be significantly reduced. Based on the multi-set numerical values, the fitting analysis of the multi-group data is carried out, the empirical model is constructed, and the matching relationship of the bullet-target effect is obtained. The results of the study are of great significance for the more scientific use of active material projectiles against battlefield targets, to improve the activation rate and the effectiveness of target damage.
