| 摘 要： | 采用Reddy 高阶剪切理论对正交各向异性蜂窝夹层板进行了分层研究, 推导出蜂窝夹层板的动力学基本方程, 并且对正交各向异性单向蜂窝夹层板的自由振动进行了深入的研究, 给出了对边简支时的频率方程及振型函数, 同时分析了夹芯厚度及厚跨比对其频率的影响, 并与低阶剪切理论作了比较, 结果证明高阶理论较好。

| Abstract: | In this paper, dynamic behavior of orthotropic honeycomb sandwich plates is investigated layer by layer with high order theory of Reddy. Dynamic equations of honeycomb sandwich plates are derived. Free vibration of one dimensional orthotropic honeycomb sandwich plates is investigated deeply. Frequency equations and functions of vibration mode are given when two sides, opposite to each other, are simply supported. How frequency is influenced by thickness of core and ratios of thickness to span is analyzed simultaneously. The results are compared with those of low order theory. The result of comparison proves that high order theory is better than low order theory. |
