摘    要:提出一种具有宏观负泊松比效应的新型蜂窝舷侧防护结构,通过对负泊松比效应蜂窝胞元特殊结构构型设计,实现中等弹速下良好抗爆抗冲击性能。利用有限元动力学分析软件,研究鱼雷或导弹水下对舷侧防护结构的撞击侵入和穿透过程,对比研究了不同蜂窝构型、材料、胞元尺寸和胞壁厚度对舷侧结构抗冲击性能的影响。结果表明,蜂窝防护结构具有良好的抗冲击性能,负泊松比蜂窝构型较正泊松比蜂窝构型抗冲击性能更优。

关 键 词:固体力学    舰船防护结构    非线性有限元    蜂窝结构    负泊松比    负泊松比结构    抗冲击

Abstract:Broadside defensive structure is important for naval vessels to maintain vitality. A novel broadside defensive structure with macro negative Poisson’s ratio is proposed to achieve higher anti-shock and anti-blast performance by design of auxetic honeycomb configuration. The process of an anti-ship missile impinging on and penetrating broadside structure is simulated by nonlinear finite element software. Effects of different design parameters on broadside structure, like auxetic honeycomb configurations, materials, sizes and thickness of honeycomb cell, are studied and compared. Numerical results indicate that counter-impingement capacity can be improved by adoption of auxetic broadside structure, and honeycomb cell with negative Poisson’s ratio is better than that of common honeycomb cell on anti-blast performance.
Keywords:solid mechanics  ship defensive structure  nonlinear finite element  honeycomb structure  negative Poisson's ratio  auxetic structure  anti-shock
