説明

Rotating sound field excited by flexural vibration disk/ring is used for some high-power ultrasonic applications. In general, two or more transducers are used for this purpose with changing the number or position of transducers. When the transducers are attached to the disk/ring, the vibration distribution in the disk/ring does not exactly match the natural mode of vibration. This paper presents a quantitative evaluation of this difference in flexural vibration distribution of the disk driven by Langevin transducers.
