在串联战斗部的前级聚能装药结构中加入衬筒,运用ANSYS/LS-DYNA有限元软件,研究衬筒、起爆方式和两罩材料对两段侵彻体性能的影响。结果表明:对于设计的前级聚能装药结构来说,无衬筒时不能形成有效前段侵彻体,反之,加入衬筒后可形成有一定头尾速度差的两段侵彻体,且衬筒直径为20~25 mm(0.35Dk左右),材料为铜时衬筒的截断作用最有效;当上罩选择锥形钛罩、下罩选择偏心亚半球钼罩,且采用双环起爆时形成的两段侵彻体性能最佳。
The liner was added to the front charge assembly structure of the tandem warhead and the influence of the liner, initiation mode and two cover materials on the penetration performance of the two sections was studied by ANSYS / LS-DYNA finite element software. The results show that for the former projectile charge structure, the effective frontal inrush can not be formed when there is no liner, on the contrary, the two invaders with some head and tail velocities can be formed after the liner is added The diameter of the liner is 20-25 mm (0.35Dk or so). When the material is copper, the liner function is most effective. When the upper cover is made of titanium cap and the lower cover is selected, The best performance of the two penetration.
