摘要

本研究对子弹对夹芯板结构的影响进行了数值研究。该研究旨在根据芯材几何形状和所用材料的类型,证明夹芯板结构在抵抗弹道载荷方面的理想性能。数值模拟采用约翰逊-库克材料模型,并应用于 ABAQUS/Explicit 软件。本研究考虑了射击目标位置和子弹攻击角等参数,以审查结构对弹道载荷的抵抗能力。研究结果表明,采用十边形核心几何结构和 Armox 500 T 材料的夹芯板结构在抵御 500-700 米/秒速度的钝头子弹冲击方面效果最佳。这项研究的贡献在于,通过显示夹层结构与子弹之间的相互作用,子弹的速度下降以及结构所能吸收的能量,让人们了解弹道学领域。总之,这项研究为改进防护结构的设计和性能提供了启示。

Analysis of the ballistic impact on sandwich panel: influence of attack angle and target location in structure–bullet interaction

This study presents a numerical investigation of bullet impact on sandwich panel structures. This research aims to demonstrate the ideal performance of sandwich panel structures in resisting ballistic loads based on the type of core geometry and materials used. Numerical simulations were conducted using the Johnson–Cook material model and applied in ABAQUS/Explicit software. Parameters such as shot target location and bullet angle of attack were considered in this study to review the structure’s resistance to ballistic loads. The results showed that the sandwich panel structure with decagon core geometry and Armox 500 T material was optimal in resisting the impact of blunt bullets at 500–700 m/s. The contribution of this research is to provide understanding in the field of ballistics by showing the interaction between the sandwich structure and the bullet through the velocity drop that occurs on the bullet and the energy the structure can absorb. Overall, this research provides insight into improving the design and performance of protective structures.
