| description | This paper deals with the vibration characteristics of a piezoelectric open-shell transducer which was made by dividing a cylindrical piezoelectric transducer longitudinally into two segments. Two-dimensional governing equations were derived by using the cylindrical membrane theory. Applying mechanical and electrical boundary conditions yielded a characteristic equation for the resonance frequencies of the piezoelectric open-shell transducer. The fundamental frequency and the electromechanical coupling factor were calculated and compared with the results of the finite element analysis and experiment. The fundamental mode shape obtained theoretically was compared with the result of the finite element analysis. The theoretical analysis was verified to provide the vibration characteristics of an open-shell transducer.
► Theoretical derivation of the vibration characteristics by using a superposition method. ► Circumferential motion at the fundamental mode. ► Smaller resonance frequencies for larger ratio of the width to radius. ► Smaller electromechanical coupling factor for larger ratio of the width to radius. |
