Abstract

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.

Key words： insensitive munition; bullet impact test; domestic 12.7 mm armor-piercing incendiary cartridge; American M2 armor-piercing cartridge; numerical simulation
