Abstract
To study effects of different explosives and charge height on penetration performance of shaped charge jets, and analyze the influence of different explosive and charge height on the penetration performance of the shaped charge jets. LS-DYNA is used for numerical simulation by modeling with TrueGrid. At the same charge diameter and the same height of the charge, the comparison of different explosives on the head velocity and the penetration of target behind the jet were made.With the same charge diameter, the same kind of explosives, different charge height of the jet head speed, the ability to penetrate the target after the target was compared. The simulation results showed that Octogen has the largest head velocity of the energy jet formed by the crushed drug cover; and the strongest ability of target penetration aftereffect. Impact of change of charge height of the formation of the energy of the head of the jet is not obvious. And the impact to penetrate the target is either. The study results have a certain reference value for the design of charge jets.关键词
