Simulation Study of Projectile Fragment Distribution under the Condition of Airburst
Based on the theory analysis to the space distribution regularity of pellet fragments,consorting with spherical target experiment and the initial velocity experiment of pellet fragments,we get the change regularity of space distribution of density and initial velocity of pellet fragments following falling speed in dynamic explosion.This paper first establishes the mathematical model of the projectile fragment distribution under the airburst condition,and then combines the results of spherical target test and projectile fragment initial velocity test to conduct the simulation analysis on the law of projectile fragment initial velocity and density with the change of falling speed,finally get the conclusion which meets the real situation.The conclusion has a guiding significance to improve the projectile structure design and to improve lethality.
