文中使用Autodyn-2D对穿甲弹冲击起爆导弹战斗部的过程进行了模拟,通过改变弹径、弹长和平头直径比并对不同工况进行分别计算,分析了以上因素对临界起爆速度的影响。利用分析结果设计了有利于引爆的220g穿甲弹弹芯尺寸。设计结果为:弹径取16~18mm,对应的弹长为49.1~62.2mm。

Autodyn-2D was used to simulate the process of armor-piercing projectile shock initiating missile warhead. By calculating different working conditions and changing projectile diameter, length and flat diameter ratio, the influence of the factors above on critical initiation velocity was analyzed. A 220 g armor-piercing projectile core part was designed in dimensions conducive to initiation using analyzing results. The dimensional design result is that the projectile diameter is 16~18 mm, the respecting projectile length is 49.1~62.2 mm.
