    Abstract
  • The damage of shaped charge jet to liquid-filled structure was analyzed by ANSYS/LS_DYNA software.The influence of liner thickness and material parameters on the performance of shaped charge warhead under water is obtained. The thickness of liner between 0.04Dk and 0.06Dk, jetting penetrator charge （JPC） has excellent penetration performance for the liquid-filled defensive structure; When $\delta $ < 0.04Dk, the JPC forming structure is poor, and the decay rate of the kinetic energy in the water is faster.When $\delta $ > 0.06Dk, the initial kinetic energy of the JPC is low, and the effect of the after-target effect is poor; It is also illustrated that among three kinds of linear materials including iron, copper and tantalum: Pure iron JPC has the highest penetration ability; Tantalum JPC has the best water storage kinetic energey performance; Copper JPC has better overall performance.
