A study of quartz tuning fork resonators in the second flexuralmode

摘要

Quartz tuning fork resonators in the second flexural mode havenbeen studied in less detail than those in the fundamental mode. It isnnecessary for quartz tuning fork resonators in the second flexural modento be carefully designed from the viewpoint of total vibrational systemndesign including the mounting leads and capsules, since vibration in thenbase portion of quartz tuning forks is more readily transmitted to thenmounting leads and the capsules as a result of the larger amplitude innthe base portion in the second flexural mode than in the fundamentalnmode. We will discuss here the characteristics in detail on the basis ofnexperimental data and theoretical analysis. Considerations are presentednin order to achieve optimal design
