N2 - In this paper, the design, construction, and operation of a magnetostrictive resonant torsional vibrator are described. To generate torsional vibration, two magnetostrictive patches are bonded on an aluminum horn. Two magnetic fields, longitudinal and circumferential, are applied into the patches. As a result, the magnetostrictive patches vibrate torsionally based on the Wiedemann effect. The magnetostrictive patches are made of 2V permendur, which has isotropic magnetic properties. The principle of the torsional vibrator is explained, and differential equations of torsional vibration of the horn are derived. A torsional horn is designed for a resonant frequency of 8515 Hz. The experimental results show that the torsional angle of the tip of the horn is 5.44× 10-6 rad. This type of vibrator is exploited in applications that require torsional vibration, such as miniature ultrasonic motors or ultrasonicassisted bone drilling system. In other words, the vibrator is used as an actuator.
