In order to provide references for the design of anti-deep penetration earth penetrating weapons, the finite element models of rod jet penetrating moving target plate with different velocity under different penetration angles were established by using ANSYS/LS-DYNA software, and the numerical simulation was carried out. The results showed that when the penetration angle was constant, with the increasement of the moving speed of target plate, the penetration ability of rod jet decreased gradually. When the moving speed of the target plate was not large, the positive penetration damage ability of rod jet to target plate was better than the intercept and chase damage ability. While when the moving speed of the target plate was large, the intercept ability of rod jet to target plate was better than the positive penetration damage ability and chase damage ability. The research results proved the feasibility that the armor penetrating warhead applied to the design of anti-deep penetration weapons and the effect of damage interception was better.
