We study thickness-shear and thickness-twist vibrations of a finite, monolithic, AT-cut quartz plate crystal filter with two pairs of electrodes. The equations of anisotropic elasticity are used with the omission of the small elastic constant c(56). An analytical solution is obtained using Fourier series from which the resonant frequencies, mode shapes, and the vibration confinement due to the electrode inertia are calculated and examined.
我们研究了具有两对电极的有限整体 AT 切石英板晶体滤波器的厚度剪切和厚度扭转振动。利用各向异性弹性的方程，并忽略小弹性常数 c(56)。利用傅里叶级数得到了一个解析解，从中计算和研究了共振频率、模态形状以及由于电极惯性引起的振动限制。
