用模拟药和可退模开合弹对不同分步压装装药工艺参数进行实验，并对装药密度和轴径向密度分布进行检测，分析分步压装工艺参数变化对最终装药密度和密度分布的影响。试验结果表明：随着螺杆直径的增大，周边和平均装药密度均呈上升的趋势；装药过程中初始压力越高，越有利于提高装药密度和密度分布，当压力达到一定值后，装药密度趋于一致；螺杆距弹体底部间距越小，底部越容易压实，密度越高；螺杆每次带入的进料量越少，压制次数越多，密度均匀性越高。该研究为加快分步压装装药工艺的推广应用打下了基础。

Analog explosive and unmoulded shot were employed to experiment the different parameters, and detection density distribution of charges and axes radial, analyzed the effect of step-press-loading technological parameter for finally charge density and density distribution. The results show that, the effects on charge density and density distribution of step-press-loading charge technology are observed obviously. The average charge densities are enhanced with the increasing screw diameters, charge quality and density distributions are also improved with the increasing pressures. When the bottom gap of shot decreases, shot bottom can be pressed more easily, and the charge density can be improved at the same time. The press frequency and density uniformity can be promoted with the decreasing charge quantity. This research will promote the use of the step-press-loading charges technological.
