| 摘 要： | 采用海37 mm弹道炮发射次口径钨合金和钨纤维增强非晶复合长杆弹进行了高速侵彻装甲钢靶试验，并借助三维非线性动力有限元程序ANSYS LS-DYNA对1.0~2.6 km/s速度条件下两种长杆弹侵彻半无限厚装甲钢靶问题进行了数值模拟，分析了弹体材料和速度对其侵彻性能的影响，并对其毁伤机理进行了初步分析.实验与数值计算结果均表明钨纤维增强非晶复合长杆弹的侵彻性能优于钨合金长杆弹；实验侵彻过程中，钨纤维增强非晶复合长杆弹产生了自锐现象，而钨合金长杆弹则是形成了蘑菇头；数值模拟结果表明两种长杆弹的破坏模式随入射弹速的变化而变化.

| Abstract: | The sea 37 mm ballistic gun was used to launch the subcalibertungsten alloy and tungsten fiber reinforced amorphous composite long rods to penetration armored steel target with high speed.A 3D nonlinear dynamic finite element program ANSYS LS-DYNA was applied to simulate these processes. The effects of the material property and velocity of projectile on the penetration performance and the damage mechanism were analyzed. The penetration performance of tungsten fiber reinforced amorphous composite long rod performs better than tungsten alloy penetrator experimentally and numerically. Experimental results show that self-sharpening phenomenon occurred during the process of tungsten fiber reinforced amorphous composite long rod penetration armored steel target, while mushroom head formed for tungsten alloy long rod; Simulation results suggest that the damage mode changes with penetration velocity. |
