摘要
本文选择一组点载静力梁函数作为基函数，应用李兹法近似求解矩形薄板的自振特性，计算了多种边界条件下各种长宽比的矩形薄板的自振频率，与其它方法相比，本文方法具有很好的精度和收敛性，且计算非常简单直接。
he Ritz method is used in this paper to solve the vibration characteristics of thin rectangular plates. By selecting a set of static beam functions under point loads as the base functions, the natural frequencies of thin rectangular plates with various boundary conditions and aspect ratios are obtained. Comparing with other conventional mothods, the mothod presented here is simpler and straightforward with high accuracy and good convergency.
