Abstract:

Ultrasound technology has become an important aspect in material handling and machining. Standing and traveling ultrasonic waves have been applied in powder transportation, feeding, dosing and supply of small amounts of powder with high quantitative accuracy and precision. Piezoelectric actuators are the most commonly used to generate the ultrasonic waves in various devices. Hence, these devices have presented a unique, economic and simple means of accurate handling of powder. This paper describes the determination of the resonant frequency of a piezoelectric ring that can be applied for generation of the ultrasonic waves. The resonant frequency is important in determining the highest amplitude of the vibration of the ring.
