Penetration of steel ingot by linear shaped charge with cuniform cove

Field Engineering Institute, PLA University of Science and Technology, Nanjing 210007, Jiangsu, China

摘要

摘要: 为了获得楔形罩线型聚能装药射流侵彻钢锭的特点和规律，利用ANSYS/LS-DYNA软件建立了三维数值计算模型，并进行了数值模拟。在此基础上，进行了实际的切割实验：对于某一炸高条件，切割深度随时间的增加先快速增加，后缓慢增加；对于不同的炸高，切割深度随炸高的增加而缓慢增加，当炸高为40~60 mm和70~120 mm时，侵彻深度表现出对炸高的不敏感性；同时，获得了不同炸高条件下不同时刻的钢锭切口断面形状。结果表明，数值模拟和切割实验结果有很好的一致性，可以用该三维数值计算模型模拟实际切割器侵彻钢靶的过程，并获得其特点和规律。

Abstract: To obtain the characteristics and the mechanisms behind the penetration of steel ingot by linear shaped charge (LSC) with a cuniform cover, we built a three-dimensional numerical model using ANSYS/LS-DYNA program and performed a numerical simulation study. The actual cutting experiment was conducted on the basis of this numerical simulation and the following results were achieved: For a given standoff, the depth of LSC cutting steel ingot increases at first rapidly along with of time and then this increase gradually slows down; for different standoffs, the depth of LSC cutting steel ingot increases more slowly with the increase of the standoff. The penetration depth changes little at the standoffs ranging from 40 to 60 mm and from 70 to 120 mm, showing an insensitivity to the variation of the standoff. Different shapes of the cutting cross-sections of the steel ingot at different time were obtained under different conditions of the standoff. The results show that the penetration results of numerical simulation were consistent with those of the cutting experiment. Our three-dimensional numerical model can simulate the process of the penetration of the steel ingot by the real cutter. The characteristics and the mechanisms obtained can better reflect the actual cutting process.
