摘要：

In order to study the output variation law of Fe-Ga transducer under different frequency magnetic fields, a Fe-Ga transducer with double excitation coil is designed. The static and dynamic output characteristics under different prestress are studied. The hysteresis characteristics at different frequencies are also studied. Through the conversion relationship between magnetic field energy and mechanical energy, the relationship between output mechanical energy and frequency is determined. The results show that under the same prestress, the static strain and output displacement gradually increase with the increase of the magnetic field and then become saturated. At the same frequency, the static strain and output displacement increase first and then decrease with the increase of prestress, and the static strain and output displacement values are the largest at 2MPa. Under the same prestress, the output displacement maximum decreases with the increase of the frequency. The maximum displacement increases first and then decreases with the increase of prestress at the same frequency. At the same frequency, the magneto-mechanical coupling coefficient is the largest when the prestress is 2MPa, and the output mechanical energy is thelar-gest too. Under the same prestress, the output mechanical energy increases first and then decreases with the increase of frequency, and then increases gradually. © 2019, Electrical Technology Press Co. Ltd.
