摘　　要：为了为反深侵彻钻地武器的设计提供参考,利用ANSYS/LS-DYNA软件建立了不同侵彻角下杆式射流侵彻不同速度移动靶板的有限元模型,并进行数值模拟。结果表明,侵彻角一定时,随靶板移动速度增加,杆式射流侵彻能力逐渐降低;当靶板移动速度不大时,杆式射流对靶板的正侵彻毁伤能力优于迎击拦截和追击毁伤能力;当靶板移动速度很大时,杆式射流对靶板的迎击拦截能力优于正侵彻毁伤和追击毁伤能力。研究结果证明破甲战斗部应用于反深侵彻钻地武器的设计上具有一定的可行性,且拦截毁伤效果较好。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.
