Simulation and experiment of key influencing factors on the ballistic performance of SiC-ultra-high molecular weight polyethylene biomimetic flexible laminated structure

  • 摘要: 基于仿生学原理构建了一种鱼鳞状的柔性叠层防护装具,仿生鳞片为中间厚边缘薄的双层复合结构,上下层分别为SiC陶瓷和超高分子量聚乙烯(UHMWPE)。采用ANSYS LS-DYNA软件的显式分析方法模拟了其防弹性能,主要从装具变形量、应力传递规律及能量耗散机制与子弹残余速度展开分析,重点研究了支撑点数量、曲率半径及覆盖角对防护性能的影响。鳞片单排与多排排列时背面垫料的凹陷深度仿真结果分别为32.52 mm和24.73 mm。本文依据NIJ标准Ш级要求对柔性防护装具进行实弹测试,结果表明试验样件在多发子弹侵彻后,出现了局部两点支撑的不利情形。该成果将对新型柔性防护装具的设计和制备具有重要意义。
