破片形状对复合靶抗侵彻性能影响的实验研究
Experimental Study on Influence of Fragment Shape on the Anti-penetration Performance of Composite Plates
摘要
Abstract
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.关键词
