摘要
聚焦式杆条战斗部的杀伤元为杆条,杆条不同的参数对战斗部杀伤效果有一定的影响。利用有限元计算软件ANSYS/LSDYNA对聚焦式杆条战斗部进行了数值模拟,分析了各层杆条数量与杆条错位排布角度对聚焦式杆条战斗部爆炸形成杀伤环的影响。结果表明:当战斗部最大口径为11 cm时,单排12段杆条战斗部毁伤效能较好,杆条绕战斗部轴线错位5°排列时杀伤元可形成一个一定宽度、连续的杀伤环。
The fragments of focusing rod warhead's are the rods. The different parameters of the rods have some effects on the damage efficiency of warhead. Focusing rod warhead is simulated by finite element software ANSYS / LSDYNA,and the influences of the number and dislocation arrangement of rods on lethal blast radius formed during explosion are analyzed. The simulation results show that the warhead with 12 rods in single-layer arrangement has the better damage efficiency,and the rods dislocatedly arranged at 5°can form a continuous lethal radius with a certain width when the maximum diameter of warhead is 11 cm.
