摘要: 车辆底盘、门板、发动机盖等受到子弹、路边炸弹、地雷等攻击后极易导致装备受损和人员伤亡,传统装甲防护结构材料可靠性和安全性受到巨大考验,研发低密度、高防护、小体积、易挂载的新型抗震防弹材料十分必要。在引入碳纤维、陶瓷、非牛顿流体等轻质新材料的基础上,本研究提出一种多材料层合防护结构材料,采用非牛顿流体切削和蜂窝单元吸能柱(螺栓)切割的双切削消能模式。运用ANSYS Autodyn有限元分析仿真模拟,初步验证了该新型抗爆防弹装甲防护结构的抗弹性能。该防护结构材料能充分发挥金属、陶瓷、流体材料以及蜂窝嵌套的材料与结构组合优势,最大程度地发挥其抗爆震、抗冲击体、防火隔热等抗爆防弹能力,在提升装备和驾乘人员战场生存能力方面具有巨大潜在应用价值。Abstract: Vehicle chassis, door panels, engine covers, etc. are attacked by bullets, roadside bombs, landmines, and other attacks, which can easily lead to equipment damage and casualties. The reliability and safety of traditional armor protective structure materials are greatly challenged. It is necessary to develop new anti-seismic and bulletproof materials with low density, high protection, small size and easy mounting. Based on the introduction of new lightweight materials such as carbon fiber, ceramics, and non-Newtonian fluids, a multi-material and multi-layer composite armor structure is proposed in this study, which uses the double cutting energy dissipation mode including non-Newtonian fluid cutting and honeycomb element energy absorbing column (bolt). ANSYS autodyn finite element analysis simulation is also used to verify the ballistic performance of the new anti-explosion and bulletproof armor protection structure. This new material can make full use of the advantages of metal, ceramics, fluid materials, and honeycomb nested materials and structures, maximizing its shock wave resistances, projectile/fragment penetration, fire insulation, and heat insulation. The new material has great potential in the battlefield for protecting the equipment and soldiers.
