【摘要】 论文研究了基于负泊松比蜂窝的夹层壳的双向曲率曲面声纳罩结构构型。首先,分析了声纳罩的结构特性,提出了需求;其次,运用试验及有限元方法研究了负泊松比蜂窝的面外弯曲变形特性,结果验证了负泊松比蜂窝的同向弯曲特性,弯曲后蜂窝呈穹顶型形状;在此基础上,提出了基于负泊松比蜂窝的夹层壳结构构型。论文提出的双向曲率曲面夹层壳结构构型合理,将为新型高性能声纳罩的研制奠定理论基础。更多还原

【Abstract】 The structural configuration of a double-curvature curved sonar dome based on an auxetic honeycomb sandwich shell have been investigated in the present research.The first step is to analyze requirements and the structural characteristics of the sonar dome.Secondly,the out-of-plane bending deformation behavior of the auxetic honeycomb was numerically simulated using the finite element method.On this basis,a structural configuration for the auxetic honeycomb sandwich shell was proposed.The double-curvature curved sandwich shell configuration presented in the paper is reasonable and will lay a theoretical foundation for the development of new high-performance sonar domes.更多还原
