摘要: 针对平衡炮的具体结构特点，为了精确计算弹丸膛内过载变化过程，利用经典内弹道法对某口径的平衡炮进行了仿真计算，得出了内弹道诸元随时间的变化曲线，再根据膛压与过载的关系，推导出了过载随时间变化的曲线图，理论计算与实验结果相吻合，该计算方法可为此类火炮的内弹道参数评估和弹丸设计提供依据。

Abstract: Aimed at idiographic structure of DAVIS gun, for accurately calculating acceleration of projectile in bore, this article emulationally calculated the launch of a DAVIS gun through classical interior ballistics, acquired the interior ballistic parameters-time curves and educed the acceleration-time curve of projectile according to bore pressure-acceleration relation. The calculated results accorded with the experimental data.
