钛合金药型罩对纯铜及45钢靶的破甲特性

摘要

为了研究射流与靶板间的反应对其破甲性能的影响,选用钛合金药型罩分别对纯铜及45钢两种材质的靶板进行静破甲试验.研究结果表明:与钛合金反应不剧烈的纯铜靶板,静破甲试验后的破孔孔径较大,穿深较高;而与钛合金反应较为剧烈的45钢靶板,静破甲试验后的破孔孔径较小,穿深较低.对静破甲试验后纯铜靶板及45钢靶板进行了微观组织分析,研究了钛合金药型罩分别对纯铜靶板及45钢靶板的破甲特性及破甲机理,并探讨了射流与靶板间的反应对其破甲性能的影响.%In order to study the influence of the interaction between the jet and the target on the penetration performance,a pure copper target and a carbon steel target were penetrated by a titanium alloy shaped charge jet.The results show that both the hole diameter and the penetration depth of the pure Cu target is much greater than those of the carbon steel target.After static armor-piercing tests, the microstructures of the pure copper target and the carbon steel target around the ballistic trajectory were investigated in detail.The micro-structural analysis reveals the penetration mechanisms of the titanium alloy shaped charge liner penetrating the pure copper target and the carbon steel target,and the influence of the interaction between the jet and the target on the penetration performance.
