摘　　要：为探究一款钻地弹的侵彻能力与弹道稳定性,进行了模拟弹侵彻土壤靶的试验。得出模拟弹的侵彻深度与弹道轨迹;根据经验公式结合试验情况计算出理论侵彻深度,利用ANSYS/LS-DYNA对模拟弹侵彻土壤靶进行数值模拟,得到仿真侵彻轨迹。对比分析可知:经验公式得出的理论侵彻深度与实际侵彻深度基本一致;仿真得到的弹道轨迹与试验结果基本吻合。得出结论:模拟弹在侵彻过程中有较好的稳定性,弹道轨迹较直,具有很好的侵彻能力。To explore the penetrating performance and ballistic stability of a penetrating bomb, Experiments were carried out to simulated bomb penetrates the soil target.The penetration depth and penetration trajectory of Simulated bomb are obtained;Calculate the theoretical penetration depth of Simulated bomb according to the empirical formula combined with the test conditions;The three-dimensional nonlinear finite element software ANSYS/LS-DYNA was used to simulate the penetration of Simulated bomb into the soil target, Obtained the simulated penetration trajectory. Comparative analysis shows that: The theoretical penetration depth derived from the empirical formula is basically consistent with the actual penetration depth;The ballistic trajectory obtained by the simulation is basically consistent with the experimental results. It is concluded that the simulated bomb has better stability during the penetration process, and the ballistic trajectory is straight and has a good penetrating ability.
