Abstract: There has been considered the fluctuations inside the sensitive element of the piezogyroscope while measuring the angular velocity. The coupled electroelasticity problem for the system of the elastic piezoceramic plates and associated mass has been solved. The presence of the viscous forces during the deformation was taken into consideration. There has been investigated the influence of the plate fixation on the amplitudefrequency characteristics of the device.

Keywords: Coriolis force, angular velocity, piezoeffect, electroelasticity.
