摘要

为探讨结构形式对舰船舷侧复合装甲结构抗穿甲性能的影响，采用均质钢板前置和后置复合材料板分别模拟舰船舷侧外设和内设复合装甲结构，结合低速弹道冲击实验，分析和比较了两种结构形式组合靶板的穿甲破坏模式和抗弹吸能能力。在此基础上，得到了球头弹穿透后置组合靶板的剩余速度理论预测公式，并与试验结果进行了比较。结果表明，两种组合靶板中复合装甲板破坏模式的差异主要体现在迎弹面纤维剪切断裂的程度，而均质钢板则由于复合装甲板的影响，呈现出完全不同的破坏模式；后置组合靶板的抗弹吸能能力要大于前置组合靶板；将弹丸穿透后置组合靶板的剩余速度理论预测值与实验结果进行比较，两者吻合较好。

Abstract

To explore the influence of structural configuration on the perforation resistance of composite armor system of warship topside, low velocity ballistic impact experiments were carried out. The outer and inner composite armor systems on warship topside were simulated through homogeneous steel plates prefaced and backed by composite laminates, respectively. Failure modes as well as energy absorptions for the two types of combined targets were analyzed and compared with each other. Based on the experimental results, an equation was obtained to predict the residual velocities for the combined targets that consist of front steel plates and composite backing armors. Results show that the difference of failure modes for the composite armors in two types of combined targets mainly exhibits in the amount of sheared fibres. While the failure modes of the steel plates in two types of combined targets are distinct due to the influences of composite armors. The combined targets that consist of front steel plates and composite backing armors absorb much more energies than the combined targets that consist of front composite armors and steel backing plates. It is shown that theoretical predictions are in good agreement with experimental results for the combined targets that consist of front steel plates and composite backing armors.
