本文研究了自由固支的超磁致伸缩/压电层合板在交变电场作用下的动态电磁力学行为。该层压板是使用薄的磁致伸缩Terfenol-d和压电PZT层。采用磁场相关的磁弹性常数和畴壁运动效应分别描述Terfenol-d和PZT层的非线性行为，并采用三维有限元分析方法计算位移、应力和感应磁场。实验还测量了磁致伸缩/压电层合板在交流电场作用下的位移和感应磁场。然后进行了仿真和实验之间的比较。
This work deals with the dynamic electromagneto-mechanical behavior of clamped-free giant magnetostrictive/piezoelectric laminates under AC electric fields both numerically and experimentally. The laminate is fabricated using thin magnetostrictive Terfenol-d and piezoelectric PZT layers. The magnetic field-dependent magnetoelastic constant and domain wall motion effect were incorporated to describe the nonlinear behavior of Terfenol-d and PZT layers, respectively, and three-dimensional finite element analysis was employed to calculate the displacement, stress and induced magnetic field. Experiments were also conducted to measure the displacement and induced magnetic field for the magnetostrictive/piezoelectric laminates under AC electric fields. Comparison was then made between simulation and experiment.
