Abstract: To address the challenge of selecting and controlling critical process parameters in the ammunition press loading method, this study investigates the factors influencing the quality of drug particle pressing and forming. Using plastic bonded explosive (PBX) as a case study, the simulation experiment method is employed. By considering the characteristics of explosives, the PBX explosive powder is simplified into a compressible continuum. A three-dimensional detailed model of the explosive system is established, and finite element simulation of the pressing process is conducted. This approach aims to unveil the correlation between pressure, holding time, and the quality of the pillars. The findings indicate that this research can offer insights for the design and production of ammunition charges, holding practical value.

Keywords: compaction process; numerical simulation; polymer bonded explosives.
