摘要
本文建立了功能梯度复合材料圆柱壳的基本动力方程,给出了各类功能梯度复合材料圆柱壳固有频率的一般解析解法,并具体导出了两端简支功能梯度圆柱壳各阶固有频率解的解析表达式,十分简明、实用。
The fundamental dynamic equations of functionally graded material cylindrical shell are established. Then its general solution of natural frequencies and mode shapes for various FGM cylindrical shells is given and as an example the analytical expression of natural frequencies for cylindrical shell with simple boundary condition is presented in this paper.
