摘要

我们开发了一种分析矩形压电板三维受迫振动的方法。由于它仅利用二维有限元，所需的矩阵尺寸比使用三维有限元时所需的矩阵尺寸小得多。采用二维有限元法得到了满足驱动要求的二维强迫解和三维自由解。计算得到的矩形at切割石英板的电容特性与实测数据吻合得很好。我们还给出了一个3/spl度/旋转x切LiTaO/ sub3 /板的数值例子。

Three-dimensional analysis of forced piezoelectric vibrations of rectangular AT-cut quartz plates and X-cut LiTaO/sub 3/ plates

We have developed a method for analyzing 3D forced vibrations of rectangular piezoelectric plates. Since it utilizes only a 2D FEM, the matrix size required is much smaller than that required when using a 3D FEM. The 2D FEM was used to obtain a 2D forced solution satisfying the driving requirement and also to obtain a 3D free solution. The calculated capacitance characteristics of a rectangular AT-cut quartz plate agreed very well with measured data. We also showed a numerical example for a 3/spl deg/ rotated X-cut LiTaO/sub 3/ plate.
