N2 - In order to study the influence of the impact force on the safety of explosives during the fall of a combatant part containing water, combined with experimental test methods, a simplified simulation test model of a explosive pillar drop impact was developed using ANSYS/AUTODYN software. Meanwhile, setting material parameters, imposing boundary conditions and selecting the best observation point, obtain pressure curves for different heights, angles and shell thicknesses, a clear view of the changes in the physical quantities of the explosive column as it falls. It can be seen that the higher the height, the greater the variation in the internal velocity of the pillar and the greater the pressure exerted. The central pressure of the pillar reaches 1.5×10 5 KPa. The pressure is minimum when the explosive column falls vertically and hits the target plate, and maximum when it falls parallel to the target plate. The velocity of fall of a cased charge is about four times greater than the pressure of fall of an uncased charge. The thicker the casing, the lower the pressure on the pillar and the more effective the protection against explosives.
