Abstract

Rotating sound field excited by flexural vibration rings is used for some high power ultrasonic
applications. To produce the traveling wave in the ring as the sound source, two standing waves
excited both spatially and temporally orthogonal to each other should be superimposed in the ring
using two or more transducers. However, excitation of the ideal distribution of the standing wave
with multiple transducers, identical to the natural vibration mode of the ring, is difficult. This
paper presents a numerical simulation of rotating sound field excited by flexural vibration rings, in
particular, methods using two vibration rings, each with the standing wave, is discussed.
