Abstract :
Quartz tuning fork resonators in the second flexural mode have been studied in less detail than those in the fundamental mode. It is necessary for quartz tuning fork resonators in the second flexural mode to be carefully designed from the viewpoint of total vibrational system design including the mounting leads and capsules, since vibration in the base portion of quartz tuning forks is more readily transmitted to the mounting leads and the capsules as a result of the larger amplitude in the base portion in the second flexural mode than in the fundamental mode. We will discuss here the characteristics in detail on the basis of experimental data and theoretical analysis. Considerations are presented in order to achieve optimal design.<>
