摘　　要：为研究高应变率下ZrO_(2)增韧Al_(2)O_(3)陶瓷(ZTA陶瓷)的动态力学性能,在获取其准静态力学性能参数的基础上,利用二级轻气炮重点开展了1.0~2.5 km/s飞片正撞击ZTA陶瓷试验,获取了冲击波速度和Hügoniot弹性极限等动态参数,并分析确定了适用于ZTA陶瓷动态力学性能的JH-2本构模型参数和状态方程。基于获得的ZTA陶瓷动态力学性能参数,数值模拟研究了弹体不同撞击速度和ZTA陶瓷-超高分子量聚乙烯(UHMWPE)纤维复合结构的层叠复合顺序对其抗侵彻行为的影响规律。结果表明:陶瓷-纤维复合结构相较于单一陶瓷靶体的抗侵彻能力显著提升,在总体面密度相同的情况下,将UHMWPE纤维层合板置于靶体背弹面时,复合靶的抗侵彻性能最佳;而将纤维层合板置于迎弹面时,侵彻深度和损伤半径显著减小。In order to investigate the dynamic mechanical properties of ZrO_(2)toughened Al_(2)O_(3)ceramics(ZTA ceramics)under high strain rates,focusing on the basis of obtaining its quasi-static mechanical properties parameters,experiments of 1.0~2.5 km/s flyer plate impacting ZTA ceramics were conducted using a secondary light gas gun.Dynamic parameters such as shock wave velocity and Hugoniot elastic limit were obtained,and the parameters and state equations of JH-2 constitutive model suitable for the dynamic mechanical properties of ZTA ceramics were analyzed and determined.Based on the obtained dynamic mechanical properties parameters of ZTA ceramics,numerical simulation was conducted to study the influence of different impact velocities of projectiles and the stacking sequence of ZTA ceramics-ultra-high molecular weight polyethylene(UHMWPE)fiber composite structures on their penetration resistance behavior.The results show that the penetration resistance of ceramic-fiber composite structures is significantly improved compared to single ceramic targets.Under the condition of the same overall areal density,placing UHMWPE fiber laminates on the back surface of the target body achieves the best penetration resistance performance of the composite target.Placing the fiber laminates on the front surface significantly reduces penetration depth and damage radius.
