Abstract

In this paper, a novel transducer called MAGNETOSTRICTIVE Torsional Resonant Transducer (MTRT) is introduced. The transducer is composed of a MAGNETOSTRICTIVE horn, a stainless steel backing and housing. In this transducer a spiral magnetic field, made up of longitudinal and circumferential components, is applied to the MAGNETOSTRICTIVE horn. As a result, the MAGNETOSTRICTIVE horn oscillates torsionally according to the WIEDEMANN EFFECT. The MAGNETOSTRICTIVE horn is made of "2V PERRNENDUR", which has isotropic magnetic properties. The differential equations of the torsional vibration of the transducer are derived, and the transducer is designed for a resonant frequency of 12075 Hz. Natural frequency and mode shape of the transducer are considered theoretically, numerically, and experimentally. The effects of important parameters such as axial and circumferential magnetic fields, and torsional prestress on the torsional displacement of the MTRT are considered, and the optimum working point is determined. These are promising features for industrial applications.
