摘要

双锥聚能装药对装甲目标具有较强的毁伤效应，试验及高精度仿真对双锥聚能装药毁伤性能的改进具有重要意义。为研究不同结构及材料双锥形药型罩聚能装药对钢靶板侵彻性能的影响，设计了5种不同结构的双锥形药型罩，同时考虑不同药型罩材料（紫铜、高熵合金）及壳体对双锥药型罩聚能射流侵彻性能的影响，开展了双锥药型罩射流侵彻钢靶板的静破甲试验。基于流体弹塑性控制方程组，构造了适用于聚能射流形成及侵彻仿真的高精度欧拉算法，集成算法为计算程序并对试验工况进行模拟。数值模拟与试验结果相互对比，验证了自主构造的高精度数值方法的准确性。研究结果表明：对于不同结构的紫铜双锥形药型罩，其射流头部速度伴随着药型罩内锥角的增大而减小，射流长度逐渐变小，有效侵彻质量及侵彻深度逐渐增大。对于相同结构的紫铜与高熵合金药型罩，其聚能射流侵彻口径及穿深差异不大。高熵合金射流头部速度更大，侵彻口径从上到下较为一致。

Abstract

The double cone shaped charge has a strong destructive effect on armored targets. Tests and high precision simulations are of great significance for improving the destructive performance of shaped charge. To study the effect of different structures and materials of conical shaped charges on the penetration property of steel target plates, five kinds of biconical shaped charge liners with different structures are designed, and the influence of different materials (copper and high entropy alloy) and shell on the penetration properties of biconical shaped charge jet are considered. The static armor-piercing test of the shaped charge jet penetrating the steel target plate is carried out. Based on the fluid elastoplastic governing equations, a high-precision Euler algorithm for the formation and penetration simulation of shaped charge jet is constructed, and the numerical simulation of the experimental conditions is carried out with the constructed program. The reliability of the self-constructed high-precision numerical method is verified by comparison of numerical simulation and experiment. The results show that the head velocity and length of the jet decreases with the increase of the inner cone angle, while the effective penetration mass and penetration depth increase gradually. For the copper and high-entropy alloy shaped charge liners with the same structure, the difference in penetration diameter and depth is not significant. The head velocity of the high-entropy alloy jet is larger, and the penetration diameter of the high-entropy alloy is more consistent from top to bottom.
