摘要
采用LS-DYNA有限元分析软件数值模拟了球形、立方形和圆柱形破片高速侵彻间隔式和叠合式多层靶板。研究表明:在高速正侵彻条件下,球形破片对多层靶板侵彻能力最强,立方形破片次之,圆柱形破片最弱;间隔式多层靶板抗侵彻能力,优于叠合式多层靶板。
LS-DYNA finite element analysis software was used.Through numerical simulation,the penetration depth of spaced and stacked multi-layered targets was obtained,under the high-speed penetrating by spherical,cubic and cylindrical fragments.It shows that the penetrating ability of spherical fragment is the strongest,the cubic fragment is the second,and the cylindrical fragment is the weakest;the anti-penetration ability of the spaced multi-layered target is better than stacked multi-layered target.
