    Abstract:

    Hollow charges usually adopt compression molding process. Using the method of continuum mechanics, a finite element simulation of the compression process model was established. First, the relative density, displacement and equivalent stress change laws of the pressing process of the JO-9159 explosive were simulated and analyzed. Then, the influences of pressing rate, initial relative density and friction coefficient on the pressing quality of JO-9159 explosive are simulated and analyzed. Results show that the JO-9159 explosive powder flows mainly in the axial direction during the pressing process, and the explosive powder flows slowly near the female mold area; when the pressing rate is 0.5 mm·s-1 and the friction coefficient is 0.25, the relative density of the charge after molding is more uniform and the amount of rebound is smaller.
