摘要
Abstract
The dynamic equation of magneto-mechanical-electric characteristics for magnetoelectric sensors is founded via Hamilton variational principles, based on the standard square equation of magnetostrictive materials and linear constitutive equation of piezoelectric materials. The magnetic hysteresis and AE effect of magnetostrictive materials for the dynamic equation are considered. The output-voltage characteristic of the magnetoelectric sensors is calculated by using the dynamic equation. The calculating results show that the model can predict the change of output voltage with time in different bias and driving magnetic fields. For example, the error between calculating result and experimental one is only 0.9%, in the bias magnetic field of 22.1kA/m, the driving magnetic field of 7.4kA/m and at the frequency of 100Hz. At same time, the model can be used to determine the maximum driving magnetic field of magnetoelectric sensors.关键词
