摘要

摘要: 为研究不同形状贫铀（Depleted Uranium，DU）合金破片的侵彻性能，首先进行了终点弹道实验，得到了圆柱形DU破片侵彻20 mm厚Q235B钢靶的终点弹道相关参数。然后通过AUTODYN软件进行了相应终点弹道仿真模拟，结果表明，仿真与实验结果基本一致，验证了仿真结果的正确性。随后又在原仿真的基础上增加了圆柱形、立方形和球形破片以不同着靶姿态侵彻靶板的数值仿真。结果表明，在相同质量和相同初速的条件下，棱角着靶姿态的立方体、楞线着靶姿态的立方体和球形破片的侵彻能力依次减弱，圆柱形和平行着靶姿态的立方形破片侵彻能力最差。若均以垂直姿态着靶，圆柱形破片侵彻能力要强于立方体，以棱角或楞线着靶姿态着靶的立方体具有更强的侵彻能力。

Abstract: To study the penetration performance of different shapes of a DU alloy fragment, we performed an experiment on a Q235B steel target with a thickness of 20 mm and obtained its terminal ballistic marriage parameters of cylindrical DU alloy fragment penetration.Then, we carried out the corresponding simulation of the key ballistic trajectory using the ANTODYN software.The results from the simulation were found to accord basically with those from the experiment, thereby verifying the simulation results as correct.Furthermore, on the basis of the original simulation, we simulated the cylindrical, cubic and spherical fragments penetrating the target plate with different target positions taken into account.The results show that, in the same quality and at the same velocity, the penetration capability of the cubic fragments in the attitude of the edges and the target cube diminishes in turn with the attitude of the target cube and the spherical fragment, with those in cylindrical and parallel attitude as the weakest.Moreover, hitting the target vertically, the cubic fragment exhibits a stronger penetration than that of the cylindrical, and it shows a better penetration capability when hitting the target in an angular or corrugated attitude.
