| 摘 要： | 建立子母弹波纹管抛撒机构的抛撒内弹道数学模型，包括抛撒药燃烧、波纹管充气和各子弹运动的变化过程。利用数值计算方法计算该抛撒机构的内弹道性能，得到燃气压力、子弹速度和子弹加速度等性能曲线。仿真结果表明，抛撒结果与试验结果符合。

| Abstract: | A interior ballistic mathematical model of steel gasbag ejection machanism of cluster munition was presented, including the processes of propellant combustion, steel gasbag charge, and bullet dispersion. The interior ballistic performances of this system were calculated to obtain the pressure in pressure chambers, the velocity and acceleration of submunitions using a simulation method. The simulating results show that the dispersing results by simulating are similar to those by testing. |
