摘要

本文基于微分正交法(DQM)对混合多尺度圆柱板进行了非线性振动分析。在考虑单向取向纤维和随机分散碳纳米管影响的三维Mori-Tanaka模型框架下，对混杂复合材料的力学性能进行了表征。考虑几何非线性，在薄壳条件下建立了圆柱板的控制方程。其次，利用DQM求解控制方程，建立了圆柱板的频率-挠度曲线。结果表明，频率-挠度曲线随碳纳米管重量分数、纤维取向、玻璃纤维体积、面板半径和碳纳米管尺寸的变化而变化。

Nonlinear vibration behavior of hybrid multi-scale cylindrical panels via semi numerical method

Based on differential quadrature method (DQM), a nonlinear vibrational analysis of hybrid multi-scale cylindrical panels has been performed in this article. The mechanical properties of hybrid composites have been formulated within the framework of three-dimensional Mori-Tanaka model taking into consideration the effects of unidirectional oriented fibers and randomly dispersed carbon nanotubes (CNTs). The governing equations for cylindrical panels have been established with respect to thin shell assumptions taking into account geometrical non-linearity. Next, DQM has been used to solve the governing equations for establishing the frequency-deflection curves of the cylindrical panel. It will be exhibited that frequency-deflection curves change by the varying of CNT weight fractions, fiber orientations, fiberglass volume, panel radius and dimension of CNTs.
