In order to study the process of black powder densification and the effect of process parameters on densification on black powder densification, the numerical simulation of black powder compaction was analyzed under different working conditions. The black powder compression experiments was carried out and compression molding process was numerically simulated by establishing a calculation model for black powder compaction with Marc FEM analysis software. The densification law of black powder was proposed and the black powder molding displacement, relative density distribution and other relevant data was obtained. The simulation results are consistent with the experimental rules. The study results can provide a basis for formulating and optimizing the actual black powder compression process.
