摘　　要：在建立超磁致伸缩换能器轴对称模型的基础上,对在磁—机耦合场作用下Terfenol-D棒的径向应力、应变进行有限元分析,为超磁致伸缩换能器的深入研究提供了依据。Based on the axisymmetric model of giant magnetostrictive transducer,the giant magnetostrictive rod＇s radial stress and strain were analyzed with finite element method under the magneto-mechanical coupling field. It provides the basis for the further research on giant magnetostrictive transducer.
