| 摘 要： | 根据大口径机枪双头弹的运动和结构特点，描述了该双头弹完整的内弹道过程，提出了双头弹内弹道计算假设，应用双头弹内弹道计算方程，计算出了12.7mm对头弹膛内压力和两弹头速度的变化曲线，对某12.7mm双头弹，当质量、质量匹配、装药量、起动压力、药厚等参数变化时内弹道性能的影响进行了比较详细的分析，获得了一些重要结论。

| Abstract: | On the basis of characteristics of duplex ammunition in both motion and structure, the interior ballistics process and computational assumption of large caliber machine gun duplex ammunition are described. With the aid of the interior ballistics computational equations used in the cartridge,the changing curves of chamber pressure and velocity of both bullets are computed. And the effect of loading factors such as the mass of bullets, the masses' matching, the propellant mass, the starting pressure, and the propellant powder density etc. on the interior ballistics characteristics has been analyzed in detail,thus drawing some important theories. |
