通过优化排列六边形和四边形夹心胞元
以六边形和四边形的组合设计胞元结构
提出了类蜂窝夹层结构的概念并对其进行了创新构型; 基于Gibson提出的胞元理论
建立了类蜂窝夹心结构力学等效模型
并推导出了等效模型的等效弹性常数公式。以卫星结构的蜂窝夹层板作为应用实例
对类蜂窝和正六边形蜂窝夹心结构的等效力学常数进行了计算对比
结果表明:两者的等效弹性模量近似相等
然而类蜂窝夹心结构的等效剪切模量却有较大提高
同时等效密度更小
可有效减小结构的质量。对卫星结构类蜂窝夹心结构进行了数值模拟研究
验证了类蜂窝夹心结构力学等效模型的正确性。
By optimally organizing hexagons and rectangles for a unit cell structure of sandwich core
the concept of quasi-honeycomb sandwich structure was put forward to design a new type of quasi-honeycomb sandwich structure. Following Gibson's unit cell theory
the mechanical equivalent model of the quasihoneycomb sandwich structure is established and the corresponding equivalent elastic constant formula is deduced. Taking a sandwich panel in a satellite structure as an example
the equivalent mechanical constants of the quasihoneycomb structure are calculated and compared with those of the hexagonal honeycomb sandwich structure
and the results show that the equivalent elastic moduli of the two structures are approximately equal
but the quasihoneycomb sandwich structure is endowed with higher equivalent shear modulus and lower equivalent body density
thus the total structure mass can be effectively reduced. Simulation verifies the correctness of the proposed mechanical equivalent model of the quasihoneycomb sandwich structure.
