摘要

摘要: 为研究椭圆截面弹体侵彻混凝土靶规律，基于动态球形空腔膨胀理论，建立椭圆截面弹体侵彻受力模型，计算典型椭圆截面弹体阻力规律和侵彻砂浆靶深度。在此基础上，采用弹道炮发射平台，开展相同质量和长度的2种典型椭圆截面弹体及圆截面弹体垂直侵彻半无限砂浆靶实验。结果表明：理论模型能够反映椭圆截面弹体受力情况，并与实验研究结果吻合较好；椭圆截面弹体长短轴参数的改变对侵彻性能影响较为显著。

Abstract: In this work, based on the theory of dynamic spherical cavity expansion, we presented a force model of penetrating projectiles with an elliptical cross-section to study their penetration performance and, using this model, calculated the resistance of the elliptical cross section and the penetration depths. Further, we performed a series of experiments of two typical elliptical cross-sectioned and circular cross-sectioned projectiles with the same mass and length penetrating perpendicularly semi-infinite grout targets at a velocity of 700 m/s to 800 m/s. The results show that the established theoretical model reflected the force condition of the elliptical cross-section and the theoretical results agreed well with the experiment, and that the size of the cross-section had a significant influence on its penetration performance.
