针对不敏感弹药枪击试验用弹差异对试验结果的影响问题,采用数值仿真方法得到不同工况下的弹头剩余动能。结果表明:弹头攻角不超过5°时,速度为834m/s以上且带有转速的国产12.7mm穿甲燃烧枪弹侵彻不同厚度45钢靶板后的剩余动能均大于速度为850m/s且带有转速的美国M2穿甲弹侵彻靶板后的剩余动能。因此,用12.7mm口径的弹道枪枪口速度为834m/s以上的国产12.7mm穿甲燃烧枪弹代替美国M2穿甲弹进行不敏感弹药枪击试验是可行但有可能是保守的。

The influence of the difference cartridge for insensitive munition bullet impact test on the test results, the residual kinetic energy of cartridge under different working conditions is obtained by numerical simulation. The results show when the bullet angle of attack is less than 5 degrees, the residual kinetic energy of the domestic 12.7 mm armor-piercing incendiary cartridge with velocity above 834 m/s and rate after penetrating different thickness 45 steel target plate is greater than that of the American M2 armor-piercing cartridge with velocity of 850 m/s and rate. So, it is feasible but potentially conservative for insensitive munition bullet impact test to use the domestic 12.7 mm armor-piercing incendiary cartridge with velocity above 834 m/s instead of the American M2 armor-piercing cartridge.
