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。

No other music could be more suitable for a concert programme dedicated to the memory of Herbert von Karajan than Giuseppe Verdi's Messa da Requiem that was of such great importance to him throughout his entire life.

任何其它的音乐都不能比选用朱塞佩·威尔第的《安魂曲》作为纪念赫伯特·冯·卡拉扬的音乐会曲目更为适宜，这首《安魂曲》在他一生当中具有如此重要意义。

The results show as follows: Due to unfitting between the wheel tread and profile of Frog No. 9, two-point contact occurs between the wheelset and frog and the contact patches become narrow and long; the Von Mises stress and contact force in the area of the contact patch between the tread close to the flange and the frog are so great that they go far beyond the yielding limit and enter the plastic deformation stage; this will lead to serious wearing of wheelset treads and frogs.

结果表明，由于车轮踏面与9号辙叉的型面不配合，轮对与辙叉形成两点接触，且接触斑狭长，靠近轮缘处踏面和辙叉接触斑的应力及接触力非常大，其数值远远超过材料的屈服极限，进入塑性变形阶段，这将导致车轮踏面与辙叉的磨耗严重。

Von Goethe in any industry, the first step to success is in its interest.

在任何行业中，走向成功的第一步，是对它产生兴趣。
