| 摘 要： | 为研究偏心起爆子母式战斗部破片速度的增益,运用LS-DYNA对子母式定向战斗部变形和爆轰驱动破片飞散过程进行了数值模拟,模拟结果与试验结果吻合.结果表明,与中心起爆相比,在与起爆位置相对的方向上,偏心起爆战斗部增益区的破片速度明屁增加,最大增益可达10.7%.引爆点同侧的破片速度要明显小于引爆点对侧的破片速度,方位角在0°～180°方向上,破片的速度呈递增趋势. |

| Abstract: | To study the gain of the non-central cluster-type warhead fragments velocity,the numerical simulation of the cluster-type directional warhead detonation dispersion process was porformed by LS-DYNA.The simulated results were in good agreement with the test results.The results showed that in comparison with center priming,on the relative direction of detonation location the fragment gain speed in the eccentric warhead detonation zone increases significantly.The maximum gain achieves 10.7 percent.The same side... |
