本文采用理论和实验相结合的方法，研究了均匀加热、完全固支（离面）矩形板的自由振动特性。具体来说，这项工作的重点是小振幅的自然频率的行为，因为温度从环境中增加。初始几何缺陷，模态耦合，不完善的夹紧（面内）和后屈曲的影响进行了处理。理论和实验之间的比较显示出良好的一致性。
In a combined theoretical and experimental approach, the free vibration characteristics ofa uniformly heated, fully clamped (out-of-plane), rectangular plate are considered. Specifically, this work focuses on the behavior of the small amplitude natural frequencies as the temperature is increased from the ambient. The effects of initial geometric imperfections, modal coupling, imperfect clamping (in-plane) and post-buckling are addressed. Comparisons between theory and experiment show excellent agreement.
