Abstract


Ultrasounds represent mechanical vibrations with frequencies generally between 18... and 100000 Hz. Ultrasonic applications are found in destructive testing, ultrasonic cleaning, ultrasonic welding, ultrasonic machining, ultrasonic motors, sonochemistry, ultrasonic flow meters, material characterization, ultrasonography, therapeutic ultrasound, ultrasonic surgery, liposuction, water treatment, air pollution control. A great novelty at the moment is the destruction of cancer cells using the phenomenon of ultrasonic cavitation. In industry, one of the possible, but relatively little studied applications refers to reducing the friction coefficient that occurs in the wire drawing process. This article presents the analytical calculation of the main characteristics of the ultrasonic transducer and the determination using FEM of the vibration eigenmodes, useful in the ultrasonic activation of the drawing die.
