Theoretical and experimental results for the acceleration sensitivity of rectangular crystal resonators

Theoretical and experimental results for the acceleration sensitivity of rectangular AT and SC cut crystal resonators are presented. In a previous paper [1998], a detailed theoretical analysis was presented on the g-sensitivity of crystal resonators with non-circular geometry. The present study focuses on the realization of various designs taken from that analysis. Rectangular AT cut crystal resonators have been fabricated and mounted in a rigid two-ended configuration and a two-ended with overhang configuration. The effect of support spacing on the g-sensitivity for these crystals is discussed and the results are compared with conventional rigid mounting (no overhang). Rectangular SC cut crystals have also been fabricated and the effect of blank orientation on the g-sensitivity for these crystals is presented. A brief discussion of the g-sensitivity measurement technique is also presented.
