摘要:
利用LS-DYNA软件对现有93W球型破片侵彻装甲钢试验结果进行符合计算，对93W合金材料参数进行标定，基于上述数值模拟与试验结果的一致性，进一步研究了93W空心钨球对装甲钢的毁伤效能。研究发现：空心钨球的弹道极限随靶板厚度的增加而增加，且弹道极限随空心钨球孔腔直径的增加呈近似指数型增加，对靶板的开孔直径也逐渐增加；动能一定的条件下，空心钨球余速、剩余动能随孔腔半径的增加呈现先增加后减小的趋势。结果表明：合理选择孔腔直径的空心钨球，可实现余速与开孔兼顾的威力要求。
Abstract:
The LS-DYNA software was used to calculate the test results of the existing 93W spherical fragment into the armored steel, and the material parameters of the 93W alloy were calibrated. Based on the above research results, the 93W hollow tungsten ball was damaged by the armor steel. It is found that the ballistic limit of the hollow tungsten sphere increases with the increase of the thickness of the target plate, and the ballistic limit increases exponentially with the increasing diameter of the tungsten ball cavity, and the diameter of the opening of the target plate also increases gradually. With certain kinetic energy, the residual speed and residual kinetic energy of the tungsten ball increase first with the increase of the radius of the cavity, and then gradually decrease. The results show that the reasonable selection of the tungsten spheres with the diameter of the cavity can achieve the power requirements of both the storage speed and the opening.
