摘要

本文研究了具有分数律的旋转功能梯度圆柱壳的振动特性。壳层运动方程根据正交各向异性类温克勒模型建立。对于各向同性材料，层压材料和功能梯度材料的物理性能在任何地方都是相同的，它们在每个点上都是不同的。在简支条件下研究了多项式定律、指数定律和三角分数定律的影响。此外，还根据周波模式、长度-半径比和高度-半径比绘制了变化曲线。此外，在不同的角速度位置，反向和正向的频率分布有增大和减小的趋势。频率首先增加，周向波数达到最大值。用不锈钢和镍作为组成材料改变表面，研究了频率的影响。三角律的频率比其他律少。

Development of orthotropic Winkler-like model for rotating cylindrical shell: Stability analysis

Vibration investigation of rotating functionally graded cylindrical shells with fraction laws is studied here. Shell motion equations are framed according to the orthotropic Winkler-like model. For isotropic materials, the physical properties are same everywhere where the laminated and functionally graded materials, they vary from point to point. The influence of the polynomial, exponential and trigonometric fraction laws is investigated with simply supported condition. Also the variations have been plotted against the circumferential wave mode, length-to-radius and height-to-radius ratio. Moreover, backward and forward frequency pattern is observed increasing and decreasing for the various position of angular speed. The frequency first increases and gain maximum value for circumferential wave number. It is also exhibited that the effect of frequencies is investigated by varying the surfaces with stainless steel and nickel as a constituent material. The frequencies of trigonometric law is less than remaining laws.
