摘要

本文研制了一种超磁致伸缩换能器。为了改善磁路，提高换能器的振动性能，利用有限元方法对换能器进行仿真计算，重点研究了导磁块和导磁筒对换能器性能的影响，又仿真计算了换能器工作时的温升。对研制的换能器阻抗和振幅进行了测量。结果表明，随着导磁筒厚度的增加，Terfenol-D棒的磁场强度先增大后减小，磁场均匀度先减小后不变，输出振幅先增大后略有减小；随着导磁块厚度的增大，Terfenol-D棒的磁场强度和磁场均匀度增大，输出振幅也增大。与无导磁筒的换能器相比，有导磁筒的换能器的机电转换系数和输出振幅均较大，但工作相同时间后的温度较高。本文的研究提供一种对超磁致伸缩换能器的磁路结构进行设计优化，并提高其振动性能的仿真计算方法。

Abstract

A giant magnetostrictive transducer was developed. To improve the magnetic circuit and the vibration performance of the transducer, the finite element method was used to simulate and calculate the transducer, focusing on the influence of the magnetic conductive block and the magnetic cylinder on the performance of the transducer, and the temperature rise of the transducer during operation was simulated and calculated. The impedance and amplitude of the developed transducer were measured. The results show that the magnetic field strength of Terfenol-D rod increased and then decreased, the magnetic field uniformity decreased and then remains unchanged, and the output amplitude increased and then decreased slightly with the increase of the thickness of the magnetic cylinder. As the thickness of the magnetic conductive block increased, the magnetic field strength and magnetic field uniformity of the Terfenol-D rod increased, and the output amplitude also increased. Compared with the transducer without magnetic cylinder, the transducer with magnetic cylinder has larger electromechanical conversion coefficient and output amplitude, but the temperature was higher after working the same time. The research in this paper provides a simulation calculation method to optimize the magnetic circuit structure of the giant magnetostrictive transducer and improve its vibration performance.
