基于压电相和磁致伸缩相的本构方程以及弹性体的运动方程,简要推导了一维机电谐振模式下压电-磁致伸缩双层磁电复合材料横向磁电电压系数的表达式.采用相应的材料参数计算分析了Tb1-xDyxFe2-y(TDF)-Pb(Zr,Ti)O3(PZT)双层磁电复合材料的横向磁电电压系数与交流磁场频率的关系,以及复合材料的长度和压电相体积分数对机电谐振频率的影响.计算与分析结果表明,双层磁电复合材料在机电谐振频率处具有明显的磁电响应特性.当有效机械品质因数为50,在谐振频率55.2 kHz处横向磁电电压系数达到峰值11.2V·cm-1·Oe-1,是低频下峰值(281.9 mV·cm-1·Oe-1)的40倍.机电谐振频率随复合材料长度的减小和压电相体积分数的增加而上升.实验结果说明TDF-PZT双层磁电复合材料在机电谐振频率处具有显著增强的磁电效应,实际有效机械品质因数约为48.
