Abstract

To study the effect of burst height on the performance of metal jet penetration into the moving target, finite element models of metal jet penetration into the moving target with different speeds at different burst heights are established using finite element simulation software, and numerical simulation is performed. The results show that with the increase of burst height, the metal jet is elongated, the velocity of the head and neck of the jet decreases and the diameter shrinks; when the target panel is stationary, the penetration depth of the metal jet into the target panel increases continuously with the increase of burst height; when the target panel is moving, the burst height for the maximum penetration depth of the metal jet corresponding to each moving speed of the target panel is not consistent with the burst height for the static maximum penetration depth, and with the increase of the moving speed of the target panel, the burst height for the maximum penetration depth of the metal jet decreases continuously; smaller burst height ensures the speed and diameter of the head and neck of the metal jet, enhances the stability of the metal jet penetration into the moving target and the resistance to interference, and improves the penetration performance of the metal jet into the moving target.
