基于线性装药结构,在两端面顶部棱线中点同时起爆方式下,相向而行的爆轰波在装药对称面发生对撞,产生更高的爆轰压力作用于中部的药型罩上,使药型罩中形成有利于沿中线闭合的速度梯度,最终形成高速EFP。利用非线性动力学分析软件AUTODYN-3D,设计中间厚两边薄的变壁厚药型罩,边缘壁厚为0.5 mm、罩顶壁厚在1.4~2.4 mm内的6种结构,研究其EFP成型状态和各项性能参数,通过对比分析得出罩顶壁厚在1.6~2.0 mm之间侵彻体成型效果好,侵彻能力强。从而对新型高效毁伤战斗部的设计提供指导意义。
Based on the linear charge structure, in the simultaneous detonation mode with the midpoint of the top edge of the two end faces, the detonation waves in the opposite direction collide with each other on the charge symmetry plane to generate a higher detonation pressure acting on the drug-type cover in the middle , The drug-type hood is formed in the middle of the line is conducive to the closure of the speed gradient, the final formation of high-speed EFP. The nonlinear dynamic analysis software AUTODYN-3D was used to design thin-walled thick-walled medicine cover with thick middle edge and thick edge. The wall thickness was 0.5 mm and the top wall thickness was 1.4 ~ 2.4 mm. State and various performance parameters. Through comparative analysis, it is concluded that the wall thickness of the top of the hood is good for forming the penetration body between 1.6 and 2.0 mm, and the penetration ability is strong. Thus providing guidance for the design of a new type of highly efficient damage warhead.
