【摘要】 与高穿深粉末药型罩相比,大孔径粉末药型罩的研究相对较少,设计和试验难度相对较大。文章通过混凝土靶试验,对大孔径粉末药型罩研制过程中的几个主要因素进行分析,研究表明影响大孔径粉末药型罩的主要因素是基本结构、成分与颗粒级配以及药型罩成型工艺,通过控制调整这些主要因素,可以改善大孔径粉末罩的性能,达到设计要求。更多还原

【Abstract】 In comparison to powder line used in high-depth penetration perforation charge,a little attention was addressed to powder line used in the big-hole penetration perforation charge for its difficulties of designing and testing.In this paper,major factors which affect performances of powder lines were systematically studied through the penetration test against concrete target,the testing results show:the performance of powder line is affected by its structure designing,composition,proper powder arrangement,and line’s forming technique;the performance of line could be optimized to meet the design demand by adjusting above major factors.更多还原
