摘　　要：为研究大口径子母弹的抛撒机理,探讨了中心爆管式子母弹抛撒的几何模型;根据其结构特点,提出了燃气做功时子弹推力面积修正系数的计算方法,建立了内弹道抛撒模型并进行数值仿真,获得燃气压力、子弹速度和子弹加速度等内弹道性能曲线,采用正交试验法分析了抛撒药装药量、中心管炸裂压力及中心管药室容积对子弹抛撒速度的影响,结果表明中心管炸裂压力是最敏感的的影响因素,为中心爆管式大口径子母弹抛撒机构设计提供了依据。To study dispersion of large-caliber cluster munitions, the structure model of central tube bursting-type shrapnel was estab-lished. According to the feature of the structure, the calculation method of the valid thrust area was built, and an interior ballistic mathe-matical model was established, the interior ballistic performance curves of this system were got by using a simulation method. Through the analysis of orthogonal experiment, the influences of charge weight of propellant, the allowable pressure of central tube and the volume of drug room on the velocity of submunitions were got. The result shows that the influence of the allowable pressure of central tube on the ve-locity of submunitions is more. This can provide basis for constructional design of large-caliber cluster munitions.
