摘要

摘要: 通过对紫铜药型罩的静破甲威力实验和脉冲X射线照像，研究了药型罩材料的晶粒度对射流性能的影响。研究结果表明，药型罩材料的晶粒度对射流动态延伸特性有重要影响。罩材料的晶粒细化可以增加有效连续射流的长度，推迟射流断裂的时间，提高静破甲威力水平。最后讨论了晶粒度对射流性能影响的机理。

Abstract: For a given shaped charge, the effects of the grain size of a liner on the performance of shaped charge jets have been investigated with aid of fire tests and flash X-ray radiographs. It was shown from experimental results that the performance of copper liner shaped charge jets are strongly dependent on the grain size of an initial liner. The smaller the grain size, the greater the cumulative length and break-up time will be and the better is the performance of penetration. The mechanism was discussed simply.
