| 目的 研究六边形蜂窝芯材异面类静态压缩载荷的数值模拟方法及相关力学行为。 方法 基于蜂窝单元阵列的方法,构筑了单双壁厚六边形蜂窝芯材异面类静态压缩有限元数值计算模型和分析方法。 结果 借助于该模拟方法,分析计算了不同结构参数条件下单双壁厚六边形蜂窝芯材的异面变形模式、变形曲线和类静态峰应力值,并绘制了相应的图、压缩力位移曲线和数据表格。 结论 将计算结果与现有的实验和理论计算结果作对比分析可知,计算结果与已有结果吻合较好,证明了所提出的有限元分析方法的可靠性。 |

| Objective Objective Numerical simulation method and mechanical behaviors of hexagonal honeycombs cores are investigated under the out- of- plane quasi- static compression loadings. Methods A finite element ( FE) model and analysis methodology of hexagonal honeycomb cores with single or double cell walls were framed based on the honeycomb cell array. Results The FE calculated deformation modes, deformation curves and values of quasi-static plateau stresses are presented in the forms of diagrams, compressive force-displacement curves and data tables for many hexagonal honeycomb cores with different configuration parameters, which are consistent with the existing experimental and theoretical calculated results. Conclusion It is shown that the proposed FE analysis methodology is reliable. |
