Abstract

Abstract

Torsional vibration of a circular piezoelectric shell of polarized ceramics mounted on a rotationally vibrating base was analyzed.The shell is properly electroded and connected to a circuit such that an electric output is generated.The structure analyzed represents a piezoelectric generator for converting mechanical energy from angular vibrations to electrical energy.Analytical expressions and numerical results for the output voltage,current,power,efficiency and power density are given.
