本文提出了一种新型的长型磁致伸缩和压电层合板设计，其中各层沿其长度轴分别磁化/极化，并给出了模拟其行为的理论。利用压电体本构方程和磁致伸缩本构方程以及运动方程，建立了磁弹电互效应等效电路。该电路被用来预测我们的Terfenol-D/Pb(Zr1-xTix)O-3层压设计的纵向和横向磁电(ME)电压系数。结果发现，纵向的ME电压系数明显高于横向的ME电压系数(接近5倍)，并且我们的新层板设计在小的直流偏置磁场下具有显著高于其他小组以前报道的设计的ME电压系数。实验值与预测值吻合较好。
This paper presents a novel, long-type of magnetostrictive and piezoelectric laminate composite design in which the layers are, respectively, magnetized/poled along their length axes, and a theory for modeling its behavior. Using piezoelectric and magnetostrictive constitutive equations, and an equation of motion, a magneto-elasto-electric bieffect equivalent circuit is developed. The circuit is used to predict the longitudinal and transverse magnetoelectric (ME) voltage coefficients of our Terfenol-D/Pb(Zr1-xTix)O-3 laminate design. It is found that the longitudinal ME voltage coefficient is significantly higher (similar to5x) than the transverse one, and that our new laminate design has significantly higher ME voltage coefficients under small applied direct current (DC) magnetic bias fields than designs reported previously by other groups. Experimental values were found to be coincidental with predicted ones.
