摘　　要：为揭示三明治结构爆炸反应装甲(ERA)对爆炸成型弹丸(EFP)侵彻效应的影响,开展了铜质杆式EFP对披挂典型斜置角ERA主靶板的侵彻效应实验。采用脉冲X光摄影方法拍摄了EFP与ERA相互作用的图像,并获得了EFP对主靶板的剩余侵彻深度(RDOP)。实验结果表明,EFP对披挂ERA主靶板的RDOP随着ERA斜置角的增大而呈非线性下降,相对无ERA时的侵彻深度下降百分比呈指数增长的变化趋势。ERA炸药层厚度为0.027D(D为装药口径)时,当斜置角为0°和30°时,EFP的RDOP和相对侵彻深度下降百分比变化较小;当斜置角从30°增大到60°时,EFP的RDOP从0.50D减小至0.19D,相对侵彻深度下降百分比则从41%迅速增大到77%.随着ERA炸药层厚度的增大,EFP的RDOP减小、相对侵彻深度下降百分比增大。其中,ERA炸药层厚度为0.027D时的相对侵彻深度下降百分比比ERA炸药层厚度为0.018D时平均增大8%.The experiment of stretched rod copper explosion formed projectile（ EFP） formed by the shaped charge penetrating into main target add-on typical explosive reactive armor（ ERA） with different oblique angle were conducted to reveal the effect of sandwich ERA on penetration efficiency of EFP. The pulsed X-ray photographs of the interaction between ERA and EFP were obtained by flash X-ray experiment,together with residual depth of penetration（ RDOP） of residual EFP. The results show that RDOP has a nonlinear decreasing tendency as oblique angle raises. The drop of penetration depth of EFP passing through ERA exponentially increases with ERA oblique angle. When the oblique angles of ERA are0° and 30°,RDOP and drop of penetration depth keep stabile. But when it grows from 30° to 60°,RDOP declines from 0. 50 D to 0. 19 D,and the drop of penetration depth grows rapidly from 41% to77%. On the other hand,the increment of layer thickness results in a heavier reduction in RDOP and the increase in the drop of penetration depth. ERA with 0. 027 D layer thickness makes the drop of penetra-tion depth higher 8% on average than it with 0. 018 D. The reason for RDOP reduction is analyzed for researching the mechanism of action of EFP and ERA.
