为了研究钨粉粒度对钨铜粉末药型罩密度及破甲威力的影响
采用3种实验方案
利用阿基米德原理测得了粉末药型罩的压坯密度和烧结后密度
三者对比
得到钨粉粒度对压坯密度、烧结后密度及烧结前后密度差的影响;对60°药型罩进行静破甲试验后
三者相比
得到钨粉粒度对破甲深度的影响.研究结果表明:钨粉粒度在45~62μm(325~230目)之间时
在保持铜粉质量分数和粒度、工艺过程、装药结构等相同的条件下
钨粉粒度越小
压坯密度和烧结后密度越大
相对密度越大
烧结前后的密度差越小
钨破甲深度越深
破甲效果越好.
To research the influence of tungsten powder particle size on density and jet penetration power of Tungsten-Copper powder liner
green density and sintered density of powder liner were measured by Archimedes principle by three kinds of experiment schemes.The influence of tungsten powder particle size on green density
sintered density and the density difference before and after sintering could be obtained.The comparative experiments of 60° shaped charge liner revealed the influence of tungsten powder particle size on jet penetration power.The study showed that the smaller tungsten powder particle size
the smaller sintered density
green density and the density difference before and after sintering
the deeper jet penetration power
the better penetration when tungsten powder particle size was between 45 μm(325 yard) and 62 μm(230 yard) under keeping mass fraction and particle size of copper powder
process etc.
