| 摘 要： | 对两种同长度、同质量、同密度的非圆截面弹芯的侵彻性能进行了研究。结合弹芯侵彻靶板试验，建立了三维有限元计算模型。为了分析弹丸侵彻过程中一些重要参数变化规律，计算了不同初始速度时弹芯的侵彻深度，并给出随入射角不同，两种截面弹芯侵彻靶板莳深度变化。计算结果表明：在相同条件下侵彻深度随速度的增加而增大；相同速度下侵彻深度随入射角的增大而减小，在角度增大到某一定值时子弹跳飞。数值结果与试验结果吻合较好。对非圆截面弹芯的设计有一定的参考价值。

| Abstract: | The penetration performance of the two kinds of non-circular cross-sectional projectiles with the same mass,length and density was tested.The 3D finite element models were established by ANSYS/LS-DYNA analysis technology based on the tests of penetrating target plates with the projectiles.For analyzing the variation of some important parameters during penetration,the penetration depths under different initial velocities,and incident angles were calculated for two kinds of non-circular cross-sectional projec... |
