Abstract

In previous works, the authors have proposed a new method to excite the ultrasonic vibration in a metal ring. The system composed of four pairs of piezoelectric elements for torsional vibration embedded in four arcuate metal blocks has designed via finite element analysis to operate with the out-of-plane vibration mode and its traveling wave. This paper presents the method to excite in-plane/out-of-plane flexural vibration mode in an annular vibration system using the piezoelectric elements for longitudinal vibration. The system for 7th vibration mode, composed of 3-mm thick piezoelectric ceramics embedded in four 140-mm diameter aluminum blocks, was analyzed theoretically.
