摘要/Abstract

摘要： 子弹在陶瓷表面的驻留现象对于装甲防护结构设计具有重要意义。开展陶瓷复合结构抗侵彻特性试验和数值模拟研究，分析侵彻作用过程中弹靶失效破坏、子弹驻留时间及耗能特征，探讨子弹速度、头部形状及背板厚度对驻留效应及复合靶抗侵彻特性的影响规律。研究结果表明：尖头弹中低速侵彻陶瓷复合结构时，子弹头部将在陶瓷表面完全侵蚀，同时耗散大量能量；随着子弹速度的增加，驻留时间减短，子弹动能耗散百分比越低，子弹速度为600 m/s时驻留期间动能耗散百分比可达90%；随着尖头弹锥角增加，驻留时间及驻留期间动能耗散百分比呈先增加后减小趋势，在半锥角取45°时驻留期间能量耗散百分比最大可达80%；随着背板厚度的降低，子弹驻留时间及驻留期间动能耗散降低幅度并不明显。

Abstract: The dwell phenomenon is of great significance to the design of armor structure. In this work，the anti-penetration characteristics of ceramic composite structure were studied numerically and experimentally. The characteristic of the failure of projectile during penetration process，projectile dwell time and energy dissipation were analyzed. Moreover，the influence of projectile velocity，nose shape and backplane thickness on the dwell and anti-penetration characteristic was explored as well. The results showed that in the penetration process，the projectile nose was completely eroded on ceramic surface，and a large amount of energy was dissipated at the same time. And the results also indicated that with increase of projectile velocity，the dwell time and projectile kinetic energy dissipation percentage decreased. When the projectile velocity is 600 m/s，the energy reduction percentage during the dwell period is up to 90%. As the cone angle of the projectile nose increases，the dwell time and kinetic energy dissipated during dwell show a trend of first increasing and then decreasing. And the energy reduction percentage during dwell period is about 80% when the half cone angle is 45°. In addition，as the thickness of the backplane decreases，the dwell time of projectile and the reduction of kinetic energy dissipation during the dwell did not change significantly.
