N型反应装甲对射流干扰的数值模拟研究
Numerical Simulation Study of N-Shaped Reaction Armor to Jet Interference
摘要
Abstract
To improve the jet protection of the explosive response of the armor to the penetration,a N-shaped reactive armor interference penetration model was designed.The effect of the angle of incidence and the angle between the plates of the N-shaped detonation reaction armor on the penetration of the jets was analyzed by numerical simulation software LS-DYNA.ANSYS/LS-DYNA dynamic analysis soft-ware is used to model.Reproduce the whole process of N-shaped reaction armor interfering with the jets.According to velocity changes of shaped jets at different angles of N-shaped reaction armor,the morphological changes of the jets and post-effect wear depth can be used to judge the interference effect of the N-shaped reaction armor on the jets.The experimental results show that with the increase of the angle between the plate charges in the N-shaped reaction armor,the protective ability of the N-shaped reaction armor increases first and then decreases.When the included angle was 13°,the reaction armor has the strongest interference with the shaped jet.关键词
