| 摘 要： | 为提高切割式多破片战斗部对目标的打击概率,在试验研究的基础上利用LS-DYNA仿真软件研究了切割网栅参数对战斗部发散角的影响。研究表明:随着切割丝安装距离的增加,破片发散角逐渐减小;相对于圆柱形,截面形状为楔形的切割丝切割效率更高,单位长度发散角变化值更小。

Influence of Incisive Cover Factor on Radial Dispersion Angle of A Incised Multiple Fragments Warhead |
| |
| Abstract: | In order to improve the hit probability of incised multiple fragments warhead, based on the experimental results, the influence of incisive cover factor on radial dispersion angle was analyzed by LS-DYNA. The result shows that as the distance between incisive cover and liner increasing, the radial dispersion angle decreases. And cutting efficiency of wedge-shaped incisive cover is better than that of cylinder, as well as the change value of radial dispersion angle per unit length is smaller. |
