摘要:
为了研究复合双药型罩结构在冲击爆炸反应装甲（ERA）后剩余射流的性能，以及对主装甲的后效毁伤作用，运用ANSYS/LSDYNA有限元分析软件，分别研究射流以垂直和倾斜两种状态冲击引爆ERA。其中，侵彻斜置ERA对射流性能影响较大，而垂直侵彻时射流未断裂，且长度几乎没有变化。在相同炸高处，与普通偏心亚半球单罩结构对主装甲的毁伤情况进行对比，结果表明：当在主装甲前未添加ERA时，复合双药型罩结构对主装甲的侵彻性能优于偏心亚半球单罩结构；而在主装甲前添加ERA后，复合双药型罩结构穿过ERA后依然可以有效地对主装甲进行侵彻，但偏心亚半球单罩结构在侵彻ERA后射流形态变化巨大，离散为射流粒子，几乎丧失了继续侵彻的能力，即复合双药型罩结构不仅可以更加有效地摧毁ERA，且对主装甲的后效毁伤效能明显提升，与单罩结构相比，扩孔孔径增加27.5%，侵彻深度提升了112.2%。
Abstract:
The finite element analysis software ANSYS/LS-DYNA 3D was used to simulate the penetrating process to study the performance of residual jet after impacting of a new composite liner structure in ERA, and the aftermath to the main armor damage. The jet with vertical or inclined shock initiation to ERA was studied respectively. Oblique penetration to ERA has a great influence on the performance of the jet, while the vertical penetration will not break the jet and not bring any change to its length. At the same burst height, the damage of the main armor was compared with that of the normal singleliner structure. Results show that when ERA is not added in the main armor, the new composite liner structure on the penetration performance of the main armor is better than the single eccentric sub hemisphere cover structure, and in the main armor before the addition of ERA, the new composite liner structure still can effectively carry out the penetration to the main armor.But eccentric sub hemisphere single cover structure great changes in the form of jet penetration ERA, discrete jets of particles, and almost lost the ability to continue penetration. The results show that the new compound liner structure significantly improved the damage efficiency of the main armor after detonating the ERA and the aperture of the reaming hole was increased by 27.5% and the penetration depth was increased by 112.2%.
