This paper mainly consists of three parts:(1) Based on the Reddy's higher-order shear deformation plate theory and general von Kármán-type equations, put forward the governing equations of pre- and post-buckled vibration of several hybrid FGM plate forms which have not been studied adequately, triumphantly applying the perturbation technique combined with Galerkin method into equations solving, and get the comparatively simple result forms with complicated deduction at last;(2) As a new type of materials, piezoelectric fiber reinforced composite actuators were applied to optimal vibration control, interrelated informatons be depicted in this paper;(3) During the investigative cource, some factors not been considered adequently in other researches were discussed fully in the postbuckled vibration analysis, such as the temperature-dependent material coefficients, heat conduction and nonlinear vibration characteristic etc.
本文的研究工作主要包括:(1)基于Reddy高阶剪切变形板理论和广义Kármán型方程,给出了几类现有研究成果较少或没有彻底解决的FGM混合板结构的屈曲前和屈曲后振动特性研究的控制方程,成功将摄动-Galerkin混合法应用于求解过程,并给出了各控制方程相对直观且易于计算的解析解形式;(2)单向压电纤维增强复合材料(Piezoelectric Fiber Reinforced Composite,简称PFRC)是一种新型压电材料,本文将其应用到了结构振动控制研究当中,发现通过压电纤维体积含量的选择可以实现混合板结构的优化振动控制;(3)围绕几种有代表性的FGM混合板结构,讨论其屈曲后的振动特性,在分析中同时考虑热传导,材料物性参数的温度相关性,以及机/热/电荷载耦合效应对非线性振动特性的影响,最后给出了大量数值计算结果。
