摘　　要：针对当前聚合物基含能材料装填过程中存在的人机面对、手工作业等问题,采用立式螺旋挤注装填工艺来实现高黏塑性浆料的连续装填。为此,本文在解析高黏浆料特性的基础上,对螺杆构型及机筒结构进行仿真优化。结果表明,相较于混炼元件在改善粒子掺混效果时会造成高剪切、高温升等隐患,三段式螺纹结构更适用于高黏含能浆料的稳定、安全输送。同时,将口模尺寸与机筒锥角分别设为直径30 mm以及1°均可以显著降低流道的阻滞作用,从而削弱高压高温等隐患以确保工艺安全性。To solve the problem of human⁃machine interaction and manual operation in the charging process of polymer⁃based high⁃viscous slurry,a vertical spiral extrusion⁃charging process was adopted to obtain a continuous loading of ener⁃getic slurry.Based on analyzing the characteristics of the high viscous slurry,the screw configuration and barrel structure were simulated and optimized.The results indicated that pineapple head mixing element not only improved the particle⁃mixing effects but also caused hidden dangers such as a rise in high shear and high temperature.Therefore,this mixing ele⁃ment is not suitable for the stable and safe transportation of a high⁃sensitivity slurry.Meanwhile,the blocking effect of the flow channel was significantly reduced by setting the size of the die and the cone angle of the barrel to beΦ30 mm and 1°,respectively.This could weaken the hidden dangers such as high pressure and high temperature to ensure process safety.
