摘要为探究蜂窝铝夹芯板的抗侵彻性能，对Ø6mm钨球侵彻蜂窝铝夹芯板进行了试验研究，得到弹道极限速度为169m/s；为了进一步比较侵彻蜂窝铝夹芯板抗侵彻规律，使用LS-DYNA进行数值模拟，将不同形状破片侵彻蜂窝铝夹芯板与间隔铝靶进行分析比较，并通过数值模拟与改进后的De Marre公式对2A12等效靶厚度计算结果进行了对比分析，结果为：抗球形破片侵彻最差，夹芯层可增加靶板约18% 的强度；数值模拟的等效2A12铝靶厚度为1.30mm，理论计算为1.33mm，相对误差在5%以内，可以满足工程计算要求。研究结果可为反卫星和反航天目标战斗部的设计提供一定的参考。

Abstract：In order to explore the anti-penetration performance of the honeycomb aluminum sandwich panel, an experimental study was carried out on the penetration of the Ø6mm tungsten ball into the honeycomb aluminum sandwich panel, and the ballistic limit speed was 169m/s;In order to further compare the anti penetration law of penetrating honeycomb aluminum sandwich panel, LS-DYNA is used for numerical simulation to analyze and compare the penetration of fragments with different shapes into honeycomb aluminum sandwich plate and spacer aluminum target,and the equivalent target thickness of 2A12 is analyzed by numerical simulation and improved de Marre formula,The results show that the penetration resistance of spherical fragments is the worst, and the sandwich layer can increase the strength of the target by about 18%;The equivalent 2A12 aluminum target thickness of numerical simulation is 1.3mm, and the theoretical calculation is 1.33mm. The relative error is less than 5%, which can meet the requirements of engineering calculation.The research results can provide some reference for the design of anti satellite and anti space target warhead.
