| 摘 要： | 利用板的挠曲面微分方程和振型方程在数学上及力学上的相似性，提出了分析矩形板固有频率的功的互等定理法。通过设定满足位移边界条件的振型函数并进行适当的转换，可方便地得到固支矩形板自由振动的频率方程。

| Abstract: | The paper applies the reciprocal theorem to the analysis of natural frequency for fixed rectangular plates. Taking into account the resemblance of deflection equation with free vibration equation, one caneasily obtain the natoral frequency equation, after supposing the form of free vibration and transforming it. |
