针对高速弹靶作用时穿甲弹芯发生变形及破碎的现象
设计一种两级分段弹芯结构
采用有限元仿真软件对两级弹芯结构侵彻陶瓷/钢复合靶板进行数值模拟。根据弹靶作用过程中的弹靶破坏模式、两级弹芯结构的运动规律
对侵彻过程进行阶段分析
并在此基础上探讨弹芯长度比例、间隔距离等因素对两级弹芯结构侵彻性能的影响。研究结果表明:两级弹芯结构较普通弹芯的侵彻深度增加率可达到16%以上;两级弹芯长度比例和间距对侵彻效果影响较大
选择合理的长度比例和间距有助于提高两级分段弹丸对陶瓷/钢复合靶板的侵彻性能;研究结果为两级分段弹芯的设计及应用奠定了基础。
A two-stage segmented core structure is designed for the phenomena of deformation and fragmentation of armor-piercing core during the impact of a high-speed projectile on a target plate
and the finite element analysis software is used to numerically simulate the penetration of two-stage core structure into the ceramic/steel composite target plate. The stage analysis of the penetration process is carried out based on the damage pattern of target and the motion law of two-stage core structure
and the influences of core length ratio
spacing and other factors on the penetration performance of two-stage core structure are discussed. The results show that the increase in the penetration depth of two-stage core structure can reach more than 16% compared with that of the ordinary core. It is found that the length ratio and spacing of two-stage cores have a great influence on the penetration effect
and the selection of reasonable length ratio and spacing can help improve the penetration performance of two-stage segmented projectiles on ceramic/steel composite target plates.

The primary objective was the determination of the effect of layering and the delineation of the ballistic limit of various combinations. In addition, a study of the erosive effect of the ceramic was executed. It was found that, on the basis of areal density, metal plates prefaced by ceramic materials are ballistically more inefficient than purely metallic targets in the low velocity range, while the reverse was found at speeds above 250 m/s. The eroded length was found to be related to the velocity of the projectile and the thickness of the ceramic layer. The projectile displacement data were found to be in very good accord with the results obtained from a previously utilized analytic force history taking into account the erosion process. The energy required to erode the projectile was found to be several orders of magnitude greater than that consumed in the fracture process of the frontal ceramic plate.

(in Chinese) DOI: 10.12382/bgxb.2022.0460 http://doi.org/10.12382/bgxb.2022.0460 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.
