| 摘 要： | 为研究铀钛破片的冲击侵彻特性，基于弹道驱动试验平台，测试了钛质量分数为0.5%~1.0%的5种典型钛合金破片对10 mmA3钢板的侵彻性能，获得了5种不同质量分数钛的铀钛合金破片对钢靶板侵彻前后的速度、质量、动能变化数据. 实验结果表明，铀钛合金破片侵彻钢靶时发出明亮火光，靶板的破坏形式以冲塞为主，并伴随有延性扩孔现象. 此外，钛质量分数为0.9%的破片动能损失最小，钛质量分数为0.75%的破片对靶板造成的剪切破坏最大.

| Abstract: | Uranium-titanium alloy fragments are characterized by high density and impressive penetration capability. Based on the fire gun driving platform, five kinds of typical fragments with titanium content of 0.5%~1.0% were tested with the fragments penetrating into target of A3 steel plate to study penetration features of uranium-titanium alloy fragments. The terminal ballistic characteristics of uranium-titanium alloy fragments penetrating steel target were obtained. And mass, velocity and kinetic energy changes of different recipes after fragments penetration were studied in the experiments. The experiments show that bright light is produced as main penetrator hitting target. Damage form of steel plates mainly is plugging and combines with ductility penetration. Furthermore, fragment of titanium content of 5% has the minimum loss of kinetic energy. Fragment of titanium content of 0.75% can cause most serious shear damage. |
