Research Abstract

In order to realize the higher-power ultrasonic transducers, the stress concentration at the nodal part of the vibration mode should be reduced because the ultrasonic output power is limited this concentrated stress. In this research, by replacing the conventional single mode vibration transducer to the multi-mode transducer the concentrated stress was distributed. And as a result much larger saturated vibration velocity was successfully demonstrated.
