摘要 Alekseevskii-Tate（A-T）模型广泛应用于长杆弹超高速冲击的终点效应分析中。A-T模型对于金属弹靶强度有明确的表达式，而对于陶瓷靶体强度尤其是弹体初始冲击速度大于1500m/s时还没有统一的结论。基于长杆钨弹超高速（1500~5000m/s）侵彻三种陶瓷（AlN，B4C，SiC）/铝复合靶体的缩比逆弹道实验数据；基于A-T模型，给出了上述陶瓷材料在不同侵彻速度范围内的靶体强度表达式。进一步通过与47发长杆钨弹超高速（1250~2500m/s）侵彻陶瓷（AlN，B4C，SiC，AD85）/RHA钢复合靶体DOP实验数据对比，验证了提出的陶瓷靶体强度表达式的适用性。

Abstract：Alekseevskii-Tate (A-T) model is widely used in the terminal ballistic analysis of long-rod projectiles hypervelocity penetrations. The explicit expressions for both strengths of metallic projectile and target in a A-T model were proposed previously. However, there was no uniform conclusion for the strength of ceramic targets in a A-T model, especially, when the initial impact velocity of projectiles was larger than 1 500 m/s. Based on reduce-scaled reverse ballistic test data of long-rod tungsten projectiles hypervelocity (1 500~5 000 m/s) penetrating into three ceramic (AlN,B4C, SiC)/aluminum composite targets, by using A-T model, the expressions of the above three ceramic targets' strengths under various projectile impact velocities were obtained. Furthermore, by comparing the above test data with the DOP tests data of 47 long-rod tungsten projectiles' hypervelocity (1 250~2 500 m/s) penetrating into ceramic (AlN,B4C, SiC, AD85)/RHA steel blocks targets, the applicability of the proposed expressions of ceramic strength were validated.
