Abstract
One-dimensional equations for coupled inplane extensional and flexural vibr ations of a piezoelectric ring are derived. The equations are used to analy ze a ring piezoelectric gyroscope. Free and forced vibration solutions are obtained. Resonant frequencies and voltage sensitivity as well as their dep endence on rotation rate and other parameters are examined.
