摘要
为得到飞行稳定性较好的尾翼型爆炸成型弹丸。文中利用有限元分析软件,对三种药型罩结构的成翼过程进行数值模拟,对比计算结果得知,药型罩外表面周向对称刻槽且槽内有填充物时成翼效果较优。继而改变槽深、槽宽等参数,并以不同材料填充槽体进行计算。结果表明:槽深、槽宽等均对侵彻性能影响显著,且填充45钢,槽宽为0.048倍、槽深为0.038倍装药直径时,具有较大的侵彻速度和长径比,尾翼成形效果较好。
In order to obtain the fin type explosively formed projectile with better flight stability, this thesis utilized finite element analysis software, and the numerical simulation of three kinds of wing formation process of liner structure was carried out. Comparing with the computing result, the forming fins effect was better when the outer surface of the liner was symmetrically cut and there were fillers in the tank. Then the parameters such as groove depth and groove width were changed, and the tank was filled with different materials for calculation. The conclusion indicated that the groove depth and groove width had remarkable influence on penetration performance, and it was filled with 45 steel. When the groove width was O. 048 times the charge diameter and the groove depth was 0. 038 times the charge diameter, it had bigger penetration speed and aspect ratio, and the fin forming effect was better.
