小口径榴弹局部改性控制破碎模拟试验研究

Local modified and controlled fragmentation experimental study on small caliber grenades

利用模拟弹对高能束局部改性工艺参量与破碎参量之间的关系进行研究,采用摸拟弹内部改性处理和外部改性处理两种方式比较裂纹源产生部位对破碎参量的影响,通过优化后的弹体处理工艺,研究能量密度、材料硬度与破碎参量的关系,实弹对比显示,高能束局部改性工艺可以满足小口径榴弹破碎性的要求。

The relation between high - energy - beam local property modified technique and its fragment is investigated using simulation shell. The influence of crack source location on fragment is compared by interior modified technique and exterior modified technique. It is proved that hing - energy - beam local modified technique can meet the fragmentation requirement of small caliber grenades.
