几种结构的圆弧杆式战斗部的数值模拟

摘要

为了探究在同一起爆下几种错位角度结构战斗部的表现特征及速率是否相同,利用有限元软件ANSYS/LS-DYNA对其进行数值模拟,动态再现圆弧杆从起爆到形成杀伤环的全过程.模拟结果表明:与错位角为0°的战斗部相比,错位角为5°或25°与错位角为10°或20°的周向圆弧杆条间隙互相补充并且间隙小;任一时刻每种结构战斗部均表现为"体"杀伤域;几种战斗部的杀伤元圆弧杆的平均速度基本相同.%To verify if the features and rate can be the same with different dislocation angle but the same initiation, use finite element software ANSYS / LS-DYNA to carry out numerical simulation, simulated the whole process of arc rod which from the ignition to the formation of the kill ring. The simulation indicates that compared with the one whose misalignment angle is 0°, the ones whose misalignment angle is 5°, 25°, 10°, 20°are more likely to have smaller gaps for cycle arc rods and they can be complementary; at any time, each warhead forms "volume" killer domain; the average velocity of several killing elements of arc rod is basically the same.
