【Abstract】 In this paper, a highpower rareearth longitudinalvibration transducer is modeled with the finite element software ANSYS. With the mechanical, electromagnetic and coupledfield capabilities available in ANSYS, electromagnetic and vibration characteristics of the transducer are analyzed, including comparison between several magnetic circuits, modeling of the magnetostrictive effects, longitudinal vibration modes and impedance in the air.更多还原
