Abstract

Aiming at a certain ball-lacking shaped charge liner structure with equal wall thickness, 3D numerical simulation for jetting projectile charge (JPC) forming and concrete-penetrating process was performed by using the software LS-DYNA 3D.Based on the analysis of influencing factors of rod jet forming and penetration performance, 3 influencing factors of shaped charge liner wall thickness, charge height and initiation diameter, and 5 evaluation indexes of jet head and tail velocities, head and tail velocity difference, jet length and penetration depth were determined using the orthogonal test method, and the sensitivity of each influencing factor to evaluation indexes was analyzed.The results showed that the shaped charge liner wall thickness is the main factor affecting jet head and tail velocities, the relation curve increases monotonously; its initiation diameter has a smaller effect on jet tail velocity, it is the main factor affecting jet head velocity, head and tail velocity difference and jet length, the relation curve increases monotonously; the charge height has the least effect on jet head and tail velocity difference; the jet penetration ability increases monotonously with increase in each factor level, but its increase gradually weakens.
