| 摘 要： | 为了研究炸高因素对聚能装药侵彻深度影响,文章建立了柱锥结合罩型聚能装药侵彻靶板仿真计算模型,研究了不同炸高条件下射流侵彻45#钢靶板的作用过程,并与试验结果进行了对比分析。结果表明,试验与数值模拟结果较吻合;柱锥结合罩型聚能装药的有利炸高与装药直径之比为1.4～1.8,最大破甲深度约为装药直径的4.6倍。

| Abstract: | In order to study the relationship between standoff distance and the penetration depth,penetration process of the cylinder-cone shaped charge without shell is numerically simulated.The jet penetration to the 45 steel target at different standoff is studied,compared with the experimental results.It is indicated that numerical simulation results agree with experimental results well.The ratio of effective standoff to charge diameter for the cylinder-cone shaped charge is about 1.4～1.8,while the maximum penetration depth is approximately 4.6 times of the charge diameter. |
