摘要
本文利用富里哀级数法,把求层板振动与屈曲问题控制偏微分方程特征函数和特征根的问题转化成求矩阵特征向量和特征值的问题。并给出了一对边有转动弹性约束,另两边有横向弹性约束的正方形板的数值结果。
Using a Fourier series method,solving eigenfunctions and eigenvalues of the governing partial differ-ential equantions of titled problems is transformed into eigenvalues of thecorrespinding matrix equations.Numerical results are presented for the rectangular plates with two opposite edges elastically restrained a-gainst transtation and the others elastically restrained against rotation.
