摘要
为了研究半速12.7 mm穿甲燃烧弹侵彻条件下,陶瓷横向尺寸对其抗弹性能的影响规律以及陶瓷抗弹性能对支撑条件的响应,同时探究可实现有效防护的复合装甲结构,采用ANSYS/LS-DYNA有限元软件对弹体侵彻陶瓷复合装甲的过程进行数值模拟,并进行靶试试验验证。结果表明:随着陶瓷横向尺寸增大,其消耗弹体能量比例不断增加,当陶瓷尺寸增大至6倍弹径时,其消耗弹体能量比例基本稳定;陶瓷抗弹性能与其支撑条件相关,碳纤维对陶瓷的支撑作用大于PE对陶瓷的支撑作用;12 mm碳化硅+3 mm碳纤维+12 mm PE组成的陶瓷复合装甲可实现抗半速12.7 mm穿甲燃烧弹的有效防护。数值模拟分析结果和试验结果吻合良好,说明了数值模拟方法的正确性和模拟结果的有效性。
In order to investigate the influence of ceramic lateral size on the ballistic performance of a half speed 12.7 mm armor piercing incendiary projectile under penetration conditions,as well as the response of ceramic ballistic performance to support conditions,and to explore composite armor structures that can achieve effective protection,ANSYS/LS-DYNA finite element software was used to numerically simulate the process of projectile penetration into ceramic composite armor,and target test experiments were con-ducted to verify the results.The results show that as the lateral size of the ceramic increases,the proportion of energy consumed by the projectile body continuously increases.When the ceramic size increases to 6 times the projectile diameter,the proportion of energy consumed by the projectile body is basically stable.The bulletproof performance of ceramics is related to its support conditions,and the support effect of carbon fiber on ceramics is greater than that of PE on ceramics.The ceramic composite armor of 12 mm silicon car-bide,3 mm carbon fiber and 12 mm PE can achieve effective protection against half speed 12.7 mm armor piercing incendiary projectiles.The numerical simulation analysis results are in good agreement with the ex-perimental results,indicating the correctness of the numerical simulation method and the effectiveness of the simulation results.
