Abstract

A double-Galfenol-rods magnetostrictive transducer is designed and manufactured. This device can simultaneously generate output displacement in axial and radial direction. The output characteristics of the transducer can be analyzed by structural dynamic model. It is found that the radial resonance frequency is 1000 Hz when the two driving coils of the transducer are connected to opposite current, and the output vibrating peak values in radial and axial directions are 52 μm and 7.5 μm, respectively. The output characteristics are studied by experiments. Comparisons between the experimental and calculated results show the validity and practicability of the model. Moreover, the research can effectively investigate the effects of the bias magnetic field, excited magnetic field, and frequency on the output amplitude.
