研究特定质量钨合金球形破片对低碳钢侵彻与贯穿中的极值.针对钨合金球形破片对半无限和有限厚度低碳钢的高弹速穿甲,首先通过数值仿真得到了典型直径破片的极限侵彻深度,同时获得了球形破片直径与极限穿透厚度的关系;在此基础上,针对不同直径破片进行了穿甲实验,实验结果与数值仿真及分析具有较好的一致性,根据实验现象和数值仿真分析了不同撞靶速度下破片的破损形式.研究结果具有重要的应用价值.%The extreme values of specific mass tungsten alloy spherical fragment penetrating and perforating lowcarbon steel were studied. For armor-piercing of tungsten alloy spherical fragment against semi-infinite and finite thickness low-carbon steel with higher projectile penetration speed, firstly, ultimate penetration depth of the spherical fragment with typical diameter was obtained using numerical simulation, at the same time, the relation between ultimate pierced thickness and the diameter of the spherical fragment was gained. Based on the above results, armor-piercing tests of different diameter fragments against Q235 steel plate were done, the test results agreed well with those of numerical simulations. According to test phenomena and numerical simulations, the damage form of the spherical fragment was analyzed with different impact speed. The research results were valuable for engineering applications.
