采用系列弹道实验，研究了双层钢/铝爆炸复合靶在不同形状破片侵彻作用下的毁伤机理和抗侵彻性能。实验采用14.5 mm滑膛枪发射直径6 mm的钢质球形破片和边长4.2 mm的钢质立方体破片。基于实验结果，分析了不同形状破片侵彻下靶板的毁伤机理和破坏模式，讨论了破片形状、动能及靶板厚度分布等因素对复合靶抗侵彻性能的影响。结果表明：在球形破片和立方体破片的侵彻作用下，钢面板发生剪切冲塞破坏，铝背板发生延性扩孔破坏；复合靶板抗立方体破片侵彻性能优于抗球形破片侵彻性能；在球形破片的侵彻作用下，当靶板厚度一定时，复合靶板的抗侵彻性能随钢面板与铝背板厚度比的增大而提高，对于立方体破片则相反。

Ballistic experiment was adopted to analyze the damage mechanism and anti-penetration performance of two-layered explosively welded steel/aluminum plates impacted by spherical and cubical fragments.The 14.5mm slip chamber gun was used to launch the spherical steel fragment with 6mm diameter and cubical steel fragment with 4.2mm side length in the experiment.The in-fluences of fragment shape,kinetic energy and layer thickness distribution on the anti-penetration performance were investigated.The results show that under the penetration of spherical and cubical fragments,the damage mechanism of steel front plate is shearing and plugging,and that of aluminum rear plate is prolonging deformation,respectively.The anti-penetration performance of target penetrated by cubical fragment is better than that of spherical fragment.The anti-penetration performance of target penetrated by spherical fragment improves with the increase of the thickness ratio of steel front plate to aluminum rear plate under the constant thickness of target,however,the opposite condition for cubical fragment.
