摘要

为了实现聚能装药大开孔威力要求,针对典型钢靶和混凝土目标,对3种不同结构的聚能装药展开研究。数值模拟研究了紫铜、钛合金、铝/钛3种球缺罩的杆式射流成型、开孔及侵彻威力性能;通过静破甲试验对不同结构聚能装药开孔及侵彻威力进行测试和分析。数值模拟结果表明:内/外罩材料为铝/钛时,开孔威力较钛合金罩、紫铜罩有明显提高,其侵彻威力较钛合金罩有所提高,紫铜罩的开孔威力相对最差。静破甲试验结果表明:铝/钛复合杆式射流对45#钢靶及C35钢筋混凝土的开孔孔径较钛合金、紫铜杆式射流有明显提高,其主要原因是低熔点钛、铝的高温气化效应及与靶板介质在熔融状态下发生脆性化学反应,导致靶板抗侵彻强度降低。

Abstract

In order to achieve the power requirements of large openings for shaped charges, three different configurations of shaped charges were studied for the targets of typical steel and concrete. Numerical simulation method was used to study the performance of rod-type jet molding, hole-opening, and penetration of three hemispherical liners made of copper, titanium alloy, and aluminum/titanium. Hole-opening and penetration performance of different shaped charges were tested and analyzed by static armor breaking test. Numerical simulation results show that the power of the hole opening and penetration are obviously improved when the inner and outer garment material are aluminum/titanium, and when the cover material is copper, the power of hole opening is relatively inferior. The static armor breaking test results show that the aluminum/titanium compounding jet diameter hole opening power for steel and C35 concrete target has obviously been improved compared with titanium alloy and copper rod jet. The main reasons are low melting point of titanium and aluminum, high temperature gasification effect and the target plate medium in molten state issued by brittle biochemical reaction, resulting in the decrease of anti-penetration strength of target.
