几种钨合金破片垂直侵彻装甲钢板极限穿透速度研究

文中从理论和实验两个方面研究了战斗部中典型的预制破片钨球、钨柱和钨块对装甲钢板的侵彻性能；分析了钨柱、钨块破片因着靶姿态不同存在着不同的极限穿透速度；给出了不同着靶姿态侵彻阻力面的理论模型，推导出了计算极限穿透速度的公式，并计算了三种典型预制破片的极限穿透速度，与测试的弹道极限进行了对比。

Investigation of Tungsten Fragments of Different Shape Penetrating Armour Plate

Fragments of several shapes are researched of their penetration to armour plate, experiments are done to test the result. The penetration velocity limits of the tungsten fragments are not a fixed value but a range due to the different resistance force from target when the fragment knocking the target with different posture. The theoretical models of resistance area are set up , and the formulas of velocity limits are deduce. By the formulas, limit velocities of three shapes fragment are calculated.
