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。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 accelerationtime curve of projectile according to bore pressure-acceleration relation. The calculated results accorded with the experimental data.
