doi:10.12382/bgxb.2022.0460

Abstract

Abstract: In order to give full play to the penetration efficiency of segmented rod projectile, the LS-DYNA software Lagrangian algorithm was used to simulate the penetration of tungsten alloy long rod projectile into armored steel. The typical physical images of long rod penetration and the time history curves of important physical quantities were obtained, which verifies the effectiveness of the finite element model. Two kinds of segmented rods with length gradient distribution and diameter gradient distribution are constructed, and their penetration efficiency was compared. The results show that when the total effective length of the segmented rod projectile is fixed, the length of each segment is uniform and equal, and the penetration ability of the segmentation rod is the greatest; The penetration depth of segmented rod with diameter gradient distribution in each segment is greater than that of the segmented rod with length gradient distribution in each segment.
