高斯曲线药型罩起爆方式研究

摘要

On the basis of the domestic and overseas research on the destroying elements from shaped charge,in this paper,the payload loaded constitution using Gauss curve liners is developed.Firstly,the forming process of destroying elements is simulated using AUTODYN-2D software,and the influences of different factors on the Gaussian curve liners molding are researched including the wall thickness (variable wall thickness and iso-wall thickness) and the charge major axis.Results:for point initiation,molding effect and speed is better adapting the top center point initiation;for annular initiation,the diameter of the initiation should not be too small,and the molding effect is best when the diameter is 40 mm.%本文在对国内外聚能装药形成毁伤元研究基础上,通过高斯曲线方程,设计了一种新型药型罩-高斯曲线药型罩的聚能装药结构,利用非线性动力学软件AUTODYN-2D对高斯曲线药型罩形成毁伤元的过程进行数值仿真研究,分析了高斯曲线作为药型罩母线几何形状的优势,并对起爆方式对高斯曲线药型罩的射流成型的影响进行了研究,研究结果表明:就点起爆而言,采用顶部中心点起爆射流的成型效果和速度最好;而对于环起爆,环起爆半径不宜过小,在环起爆半径为40 mm时射流的成型最好.
