Abstract

Shaped charge (SC) is a mechanism used by defence industries as anti-armored weapon to penetrate armored plates. Numerous studies have been conducted on the shaped charged effects. However, experimental studies are limited due to great safety requirement and limited access to high grade explosive. Due to these limitations, an experimental study on a small-scale shaped charge mechanism (SCM) penetration blast test was conducted against five (5) types of target materials. The experimental data is then verified by simulation to proof that it can be used to predict the SC penetration data. This paper intent to present a comparative study on the effect of shaped charge blast conducted by simulation with the actual experimental results. In order to conduct this study, a 2D AUTODYN software were used to develop the SC blast model against five (5) types of target materials. This study concludes that the 2D AUTODYN simulations results can predict the hypervelocity penetration for all target materials compared to the experimental test with an average difference of 9.1 %.

实验室尺度聚能药超高速侵彻机理的仿真研究

聚能装药（SC）是国防工业用作反装甲武器穿透装甲板的一种机制。关于赋形电荷效应已经进行了大量的研究。然而，由于安全要求很高，获得高级炸药的机会有限，实验研究受到限制。由于这些局限性，针对五（5）种类型的目标材料进行了小型定型装药机构（SCM）穿透爆破试验的实验研究。然后通过仿真验证了实验数据，证明其可以用于预测SC穿透数据。本文旨在通过模拟和实际实验结果对装药爆破效果进行对比研究。为了进行这项研究，使用2D AUTODYN软件开发了针对五（5）种类型目标材料的SC爆破模型。该研究得出结论，与实验测试相比，2D AUTODYN模拟结果可以预测所有目标材料的超高速穿透，平均差异为9.1%。
