为研究爆炸成型弹丸(EFP)穿透钢靶后的后效威力,设计了长杆形EFP装置及对45号钢靶板的侵彻实验。采用X光摄影方法观测EFP穿过靶板后的破片云形态及飞散特性;通过测量靶板后一定距离处验证板上的穿孔,得到靶板后破片数量。从拍摄的脉冲X光照片可以看出:EFP穿透钢靶后形成的破片云形状是截椭圆形,飞散角约50°.从验证板上的穿孔可以看出:靶后破片可穿透10mm铝板,破片穿孔分布相对随机,穿孔直径近似呈正态分布特征,破片飞散角与X光观测结果一致;随着靶板厚度增大,破片飞散角均为50°,但靶后破片数量呈先增大、后减小的趋势,即存在靶后破片数量最大化的靶板厚度。从回收到的破片可以看出:靶后碎片由EFP和钢靶碎片共同构成。 |

A series experiments that the explosively-formed projectiles (EFPs) penetrate 10-40mm-thick mild carbon steel (45# steel) were designed to investigate the effect of behind armor debris(BAD) after EFP penetrating into steel target.The morphology and scattering characteristics of BAD are observed by pulsed X-ray photography,and the number and damage ability of BAD are obtained by measuring the perforation on witness target.It can be seen from the pulsed X-ray photographs that the shape of BAD presented as fragments is of partial ellipse with the scattering angle of about 50°.The perforation on witness plate shows that BAD could penetrate 10mm-thick aluminum plate,the perforation distribution is relatively random,and the diameter of hole on witness plate approximately conform to normal distribution.The scattering angle varies little with the increase in the target thickness,while the number of BAD increases first and then decreases,namely there is a target thickness that maximizes the number of BAD.It can also be seen from recovered fragments that EFP and steel target debris together constitute the BAD. |
