摘要

摘要: 为研究粉末药型罩的材料密度对其所形成的聚能射流的影响，借助Birkhoff定常模型和Gurney压垮速度理论，计算了相同装药条件下药型罩密度与其所形成的聚能射流速度、射流微粒动量与动能的关系曲线。在相同装药结构下，对W、Cu质量配比分别为0.5∶0.5和0.4∶0.6的两种W-Cu粉末药型罩，进行了射流速度测定和破甲威力实验研究。计算结果与实验结果吻合较好，表明借助Birkhoff定常模型和Gurney压垮速度理论所计算的射流密度、射流微粒动量及动能与药型罩密度的关系曲线具有一定的参考价值，增大粉末药型罩密度可有效提高聚能射流的破甲威力。

Abstract: In order to study the relation of powder liner material density and performance of the shaped charge jet, the curves of shaped jet velocity, jet particle momentum and jet particle kinetic energy with respect to the liner density were calculated under the same charge conditions, according to the Birkhoffs steady theory and Gurneys formula of crushed speed. In the same charge structure, the jet velocity and penetration power of two kinds of powder liner were tested, whose mass ratios of W to Cu were 0.5∶0.5 and 0.4∶0.6 respectively. It is found that the experimental results are well in agreement with the calculation results. Therefore, it is considered that the calculated curves have certain reference values, and the penetration power can be increased effectively by improving the density of powder liner.
