研究了磁致伸缩/压电复合材料层合板构成的磁力控制装置的动态响应。该装置利用磁致伸缩材料的逆磁致伸缩效应，使得材料的磁化强度的变化以及因此磁路中的磁力的变化可以利用施加到压电材料的电压来控制。在这里，我们比较了新设备和传统电磁铁之间的导纳和磁通（磁力）的电压感应频率响应，以确定降低设备响应的因素。复合材料的模态形状的有限元计算支持动态响应中复合材料的振动和差距中的通量之间的观察到的相关性。
We investigate the dynamic response of a magnetic force control device composed of a laminate composite of magnetostrictive/piezoelectric material. The device exploits the inverse magnetostrictive effect of a magnetostrictive material so that the variation in the magnetization of the material, and hence the magnetic force in a magnetic circuit, can be controlled with a voltage to the piezoelectric material. Here, we compare the voltage-induced frequency responses of the admittance and flux (magnetic force) between the new device and a conventional electromagnet in order to identify the factors that degrade the response of the device. A finite-element calculation of the modal shape of the composite supports the observed correlation between the vibration of the composite and the flux in the gap in dynamic response.
