摘要

基于LS-DYNA软件模拟分析了Al-Ti微叠层材料结构不同时的抗侵彻性能，研究了微叠层结构中Ti体积分数和叠层结构变化对抗侵彻性能的影响，分析不同背板材料及面密度时Al-Ti微叠层复合靶板的抗侵彻性能。结果表明，当Ti体积分数为27.7%时材料抗侵彻性能最好；?7.62 mm穿燃弹在初速为808 m/s时侵彻微叠层材料的极限厚度为12 mm

?12.7 mm穿燃弹在初速为818 m/s、488 m/s时侵彻微叠层材料的极限厚度分别为18 mm和11 mm。韧性层呈正向梯度分布的Ti/Al

Ti微叠层复合材料靶板的抗侵彻性能优于反向梯度分布及均匀分布的靶板；Al-Ti微叠层材料靶板与Q235钢背板的厚度比为2∶1时抗侵彻性能最好；Al-Ti微叠层材料与AZ31镁合金构成复合靶板的抗侵彻性能最佳。

Abstract

The anti-penetration properties of Al-Ti micro-laminated material with different structures was analyzed by numerical simulation based on the LS-DYNA software. The effects of Ti volume fraction in micro-laminated structure and laminated structure on anti-penetration performance were investigated. The anti-penetration performance of Al-Ti micro-laminated composite target with different back plate materials and surface density was analyzed. The results indicate that when the volume fraction of Ti is 27.7%

the anti-penetration performance is desirable. When the initial velocity is 808 m/s

the limit thickness of ?7.62 mm bullet penetrating the laminate material is 12 mm. When the initial velocity is 818 m/s or 488 m/s

the limit thickness of ?12.7 mm bullet penetrating the laminate material is 18 mm or 11 mm

respectively. The anti-penetration performance of Ti/Al

Ti micro-laminated composite target with positive gradient distribution of toughness layer is better than that with reverse gradient distribution or uniform distribution. When the thickness ratio of target plate to Q235 steel back plate is 2∶1

the anti-penetration performance is satisfied

and the compound target composed of Al-Ti micro-laminated material and AZ31 magnesium alloy exhibits desirable anti-penetration performance.
