摘要

基于纵向极化压电材料及纵向磁化磁致伸缩材料的压电和压磁方程与磁电元件运动方程,给出磁电元件开路电压表达式;鉴于压电材料高输出阻抗的特点,考虑测试仪器的有限输入阻抗和传输信号引线电缆电容,通过建立等效电路模型推出了非开路情况下磁电电压计算式,取不同材料参数对磁电电压进行了数值计算.研究表明,材料参数、电路参数对输出电压均产生影响.对磁伸材料两端面受非均匀偏置磁场产生外力的非自由边界磁电效应进行研究发现,恒外力作用使压电元件产生不可检测的稳恒电压.

Abstract

Based on constituent equations of longitudinally polarized piezoelectric materials and magnetized magnetostrictive materials, and equation of motion of the magnetoelectric element, the expression to calculate the open circuit voltage of the piezoelectric material is presented. In view of the characteristics of high impedance for the piezoelectric materials, and considering the capacitance of the lead cable to transfer signal, as well as the capacitance and the internal resistance of the measuring instrument, a formula to calculate the actual magnetoelectric voltage is derived by using an equivalent circuit. Taking different materials parameters, we calculate the effect of parameter variation on magnetoelectric voltage. The results show that the influence of material parameters, cable capacitance and the input capacitance and resistance of the measuring instrument on the output voltage must be taken into account. Non-uniformly biased field will yield forces on the two ends of the magnetostrictive materials and the research result shows that the constant force produced by gradient bias magnetic field will generate stabilized voltage, which is unable to be measured by the oscilloscope.
