【摘要】 对双层磁电层状复合材料进行建模并利用有限元法对其进行仿真分析。当压电层厚固定为1mm时,磁电系数随压磁层厚度的增加而增加,并逐渐趋于一个最大值3.35V/cmOe;而固定压磁层厚度为1mm时,随着压电层厚度的增加,磁电系数先增加后减小,当压电层厚度为1mm时,磁电系数取得极大值2.80V/cmOe。通过改变模型几何参数和材料参数可仿真出不同双层磁电材料的磁电系数,为磁电材料设计提供了一种有效方法。更多还原

【Abstract】 The bilayered magnetoelectric composite materials are modeled and simulated by the finite element analysis method. When the thickness of the piezoelectric layer is 1 mm, the magnetoelectric coefficient is increasing with the piezomagnetic layer’s thickness, and gradually to the max value 3.35V/cm Oe. While the thickness of the piezomagnetic layer is 1 mm, the magnetoelectric coefficient is first increasing and then decreasing with the piezoelectric thickness, when the piezoelectric thickness is 1 mm, the max value is 2.80V/cm Oe. Different bilayered magnetoelectric materials can be simulated by changing the parameters of the modeling’s geometry and the parameters of the materials, which is an efficient method for the magnetoelectric materials design.更多还原
