摘要:
为研究7.5 g圆柱体弹侵彻下,不同厚度配比的陶瓷/钛合金靶板的弹道极限速度及靶板的破坏模式,利用有限元软件ANLYSYS/LS-DYNA,对高速圆柱体弹侵彻陶瓷/钛合金结构进行数值模拟仿真,得到了弹道极限速度随陶瓷厚度和钛合金厚度变化的拟合公式,探讨了陶瓷和钛合金厚度比对结构抗弹性能的影响规律。结果表明:陶瓷/钛合金结构的破坏变形程度基本随着结构弹道极限速度的增大而增大,与增加陶瓷厚度相比,增加钛合金厚度对弹体侵蚀程度及靶板变形程度产生的影响更大; 结构的单位面密度吸能基本随陶瓷/钛合金厚度比的增大呈先增大后减小的趋势,当陶瓷/钛合金厚度比在1~2之间时,结构抗弹性能较好。
Abstract:
In order to study the ballistic limit velocity and failure modes of ceramic/titanium alloy targets with different thickness ratios under the penetration of 7.5 g cylindrical projectile,the numerical simulation of high-speed cylindrical projectile penetrating ceramic/titanium alloy target was carried out by finite element software ANLYSYS/LS-DYNA. The fitting formula of ballistic limit velocity varying with the thickness of ceramic and titanium alloy was obtained,and the influence of thickness ratios of ceramic and titanium alloy on the performance of the anti-penetration property was discussed. The results indicate that,the damage deformation degree of ceramic/titanium alloy structure increases with the increase of ballistic limit velocity. The effect of increasing the thickness of titanium alloy on the erosion degree of projectile and the deformation degree of target plate is greater than that of increasing the thickness of ceramic. The absorption energy per unit area density of the structure increases first and then decreases with the increase of the thickness ratio of ceramic/titanium alloy. When the thickness ratio of ceramic/titanium alloy is between 1~2,the structure has better anti-projectile properties.
