Modeling of the influence of static acceleration on surface wave (quartz) oscillator
Abstract
The application of a static acceleration on a quartz oscillator, working in elastic surface wave mode, is modeled. Modification of the wave propagation speed through the substrate and its frequency are studied. Experiment proves that this frequency shift depends on the nature of the substrate through which the wave is propagating, but also on its dimensions and its mode of attachment. Theory confirms and explains these results, and also shows the relationship between the stresses arising in the substrate during the acceleration and the sensitivity to this acceleration of surface wave devices.
