Summary:Acceleration sensitivity of quartz resonator is an important challenge to achieve extremely stable frequency source operating at temperatures as high as 200 degC. Previous studies of acceleration effects on a quartz resonator on simple mounts have been limited to room temperature. In this paper we present a new theoretical model to investigate the influence of different support-configurations on the acceleration effect for different doubly rotated quartz cuts for temperatures varying from 25 to 200 degC. Results are obtained for the slow (C-) and fast (B-) thickness-shear modes for these quartz cuts. The new theoretical model shows good agreement with the published measured data on the SC-, rotated X-, and SBTC-quartz cuts. Calculated results show that the mounting supports lead to an increase in the acceleration sensitivity for these cuts at 200 degC. In addition, the theoretical model suggests optimal mounting support configurations for these cuts to achieve a stable frequency source operating at temperatures as high as 200 degC.
