研究了由磁致伸缩(MS)、压电(PE)和衬底材料组成的层状复合材料悬臂梁在弯曲共振时的磁电效应。推导了三种不同的层序在短路和开路运行时横向磁电响应的解析理论，并对FeCoBSi-AlN-Si和FeCoBSi-PZT-Si复合系统的结果进行了讨论。响应优化的PE-MS层厚度比随着工作模式的变化而发生很大变化，从开路模式下接近相等的MS和PE层厚度到所有层序列的短路操作中接近于零的PE层厚度。此外，发现衬底厚度不同地影响开路和短路ME响应，产生ME响应最大值之间的漂移和反转，这取决于层的顺序。对于不同的层厚，观测到的丰富的ME响应行为，...
The magnetoelectric effect in layered composite cantilevers consisting of strain coupled layers of magnetostrictive (MS), piezoelectric (PE), and substrate materials is investigated for magnetic field excitation at bending resonance. Analytic theories are derived for the transverse magnetoelectric (ME) response in short and open circuit operation for three different layer sequences and results presented and discussed for the FeCoBSi-AlN-Si and the FeCoBSi-PZT-Si composite systems. Response optimized PE-MS layer thickness ratios are found to greatly change with operation mode shifting from near equal MS and PE layer thicknesses in the open circuit mode to near vanishing PE layer thicknesses in short circuit operation for all layer sequences. In addition the substrate layer thickness is found to differently affect the open and short circuit ME response producing shifts and reversal between ME response maxima depending on layer sequence. The observed rich ME response behavior for different layer thicknesses,...
