摘要提出了一种近似解，研究了热载荷对加肋旋转功能梯度锥壳频率的影响。材料特性和温度场被假定为梯度和变化的厚度方向。壳体采用等间距圆环加强。运动方程由汉密尔顿原理导出。假定近似解析解满足固支边界条件，然后采用傅里叶分解和伽辽金法得到频率关系。为了验证，与文献中的一些特定情况以及有限元解进行了比较。
ABSTRACT An approximate solution is presented to investigate the effects of thermal load on the frequency of ring-stiffened rotating functionally graded conical shell. Material properties and the temperature field are assumed to be graded and varied in the thickness direction. The shell is reinforced by equal interval rings. The equations of motion are derived by the Hamilton's principle. Approximate analytical solutions are assumed to satisfy clamped boundary conditions, and then Fourier decomposition and Galerkin method are applied to achieve relations of frequencies. To validate, the comparisons are made with a number of particular cases in literature and with the FEM solutions.
