摘要：

为研究活性复合罩聚能装药对目标靶后毁伤效应,开展活性复合射流作用多层间隔靶侵彻与爆炸联合毁伤性能研究。采用实验、数值模拟和理论相结合的方法,对活性复合射流侵彻多层间隔靶的毁伤行为及机理进行探究。实验结果表明,对于给定的活性复合罩聚能装药结构,与活性-铜射流相比,活性-钛射流在钢锭上形成的侵孔直径更大,穿透一定厚度钢靶后可造成后效间隔铝板严重变形甚至撕裂。基于活性复合射流对多层间隔靶的侵爆时序联合毁伤行为,建立后效铝板爆裂毁伤分析模型。仿真结果表明:铝板上的破裂孔面积与随进活性材料有效质量和动能侵孔半径均呈正相关,但二者中活性材料有效质量对其影响更显著;基于实验和数值模拟所获取的经验参数,模型可进一步预测不同活性材料有效质量、动能侵孔和靶板厚度下后效铝板爆裂毁伤面积。

Abstract:

To study the behind-target damage effects of the reactive material double-layered liner (RM-DLL) shaped charge penetrating into the target plates, the penetration and deflagration behaviors of the composite jet impacting multi-layer spaced target are studied. The experiments, numerical simulations and theoretical analysis are used to investigate damage behaviors and mechanism of the reactive composite jet against multi-spaced target plates. The experimental results show that for a given RM-DLL shaped charge structure, comparing with the reactive material-copper jet, the reactive material-titanium jet produces a larger penetration hole in the steel ingot and causes serious deformation and even rupture to the spaced aluminum plates. Based on the combined damage behaviors, an analysis model of the rupture area on the spaced aluminum plates is established. The model shows that the rupture area is positively correlated with the effective mass of follow-thru reactive material and the hole-radius formed by the jet kinetic energy, and that the reactive material's effective mass has a more significant effect on the area. Based on the empirical parameters obtained from the experiments and numerical simulations, the model can further predict the rupture area of the aluminum plates under different reactive materials' effective mass, penetration holes formed by kinetic energy, and the plate thicknesses.
