Abstract
Using X-ray topography, the distributions of deformations in the volume of two types of AT-cut quartz resonators of different sizes were obtained on laboratory and synchrotron X-ray sources. The comparison of X-ray topography data and the amplitude–frequency characteristics of the resonators was used to establish a correlation between the deformation patterns and the features of oscillatory processes for the operating modes and their harmonics, as well as for parasitic modes. A connection between vibrations at parasitic modes and their harmonics, which manifest themselves in an amplitude inhomogeneity, and the topology of the resonators has been found. The applied significance of the obtained results for the development and optimization of new designs of piezoelectric elements and the development of their manufacturing technology is pointed out.
摘要 利用 X 射线地形图，在实验室和同步辐射 X 射线源上获得了两种不同尺寸的 AT 切割石英谐振器的体积变形分布。通过比较 X 射线形貌数据和谐振器的幅频特性，建立了工作模式及其谐波以及寄生模式的变形模式和振荡过程特征之间的相关性。研究发现，寄生模式及其谐波的振动（表现为振幅不均匀）与谐振器的拓扑结构之间存在联系。研究结果对开发和优化压电元件的新设计及其制造技术的发展具有重要的应用意义。
