摘要:
为了研究药型罩锥角对某小长径比多功能战斗部破片飞散的影响,利用ANSYS/LS-DYNA模拟了不同的药型罩锥角条件下破片飞散速度和破片飞散角的变化。仿真结果表明:破片的整体飞散速度随着药型罩锥角的增大而增加,锥角每增大10°,破片整体飞散速度增加2%,因此破片杀伤威力得到提高;破片飞散角度随着药型罩锥角的增加会略微增大,提升破片对目标的杀伤面积,且破片飞散角度会整体向上偏移。后续通过静爆试验验证了数值模拟结果的准确性。可为小长径比多功能战斗部在调整破片杀伤威力方面的研究提供参考。
Abstract:
In order to study the influence of the cone angle of shaped liner on the fragment dispersion of a small aspect ratio multi-functional warhead, ANSYS/LS-DYNA was used to simulate the variation of the fragment dispersion velocity and the fragment dispersion angle under different cone angles of the liner. The results show that the overall dispersion velocity of fragments increases with the increase of the cone angle of the liner. When the cone angle increases by 10° the overall dispersal velocity of fragments increases by 2%, and the lethality of fragments increases. The fragment dispersion angle increases slightly with the increase of the cone angle of the liner, which enlarges the damage area of the fragment to the target, and the fragment dispersion angle will shift upward as a whole. The accuracy of numerical simulation results was verified by static explosion test. The research results can provide a reference for adjusting the fragment killing power of the multi-functional warhead with small aspect ratio.
