| 摘 要： | 基于ANSYS软件建立了蜂窝铝芯和蜂窝铝板的有限元模型，模拟计算了薄壁蜂窝铝芯在深度、对边距不同时受共面载荷作用下的应力强度。利用壳单元计算了蜂窝铝芯的共面弹性模量，模拟分析了同样大小的蜂窝铝板在蜂窝芯格尺寸不同情况下受共面相同载荷时的应力情况，分析结果表明选择适当的蜂窝芯格大小和深度，可以减小蜂窝芯格及蜂窝铝板所受的最大应力。分析结果有助于找到合适的蜂窝芯格尺寸以满足较大的强度要求。最后对蜂窝铝板进行了实验研究计算，实验结果和ANSYS模拟数据基本吻合。

| Abstract: | Finite element models of an aluminum honeycomb core and an aluminum honeycomb board have been set up based on ANSYS.The stress on a thin-walled aluminum honeycomb core was simulated for different depths and subtense distances.In using the shell element model to calculate the in-plane elastic modulus of the honeycomb core,aluminum honeycomb panels of the same-size suffer the same in-plane loads.The stress analysis of honeycomb panels with different cell sizes of the honeycomb cores was carried out.The result... |
