摘 要: 在对蜂窝纸板结构进行合理化抽象和假设的基础上,借助有限元分析软件ANSYS对不同尺寸结构的蜂窝纸板进行了特征值屈曲分析与谐响应分析。结果表明,当蜂窝边长一定时,随着蜂窝高度的增加,屈曲强度迅速下降,共振频率先下降后升高;当蜂窝高度一定时,随着蜂窝边长的增加,屈曲强度逐渐下降,但共振频率变化不大,且会在其右侧出现小峰,当蜂窝的边长与高度比在1:1附近时,共振频率最低,为88Hz。 In order to explore the relationship between the structures of honeycomb and its mechanical performance, eigen buckling and harmonic analysis of FEA software ANSYS were adopted. The results prove that when the edge length keeps constant, the buckling strength decreases quickly with the increasing height, while the resonant frequency rises after an initial decline. The buckling strength of honeycomb drops sharply with the decrease of edge length when the height is fixed, while the resonant frequency changes little with small peaks by the right side, and the resonant frequency fall to the bottom of 88Hz at the length-height ratio of 1: 1.
