| 摘 要： | 本文研究悬臂磁电双晶片的弯曲问题。基于三维本构方程，建立了一维磁电弹性梁的弯曲控制方程。当输入为机械荷载、电场或磁场，通过磁电弹耦合，获得了机械弯曲变形以及磁电的输出响应。结果表明双晶片的挠度及转角不仅与输入荷载相关，也受约束于双晶片的层厚此。

| Abstract: | This paper deals with the bending of magneto-electro-elastic bimorph cantilever beam.Based on threedimensional constitutive equation,the governing equation for bending of one-dimensional magneto-electro-elastic beam is established.Under the condition that the beam is subjected to mechanical loading,electric field and magnetic field,the deflection,rotation angle and output responses of bimorph can be obtained according to magneto-electro-elastic coupling effects.It is found that the deflection and rotation a... |
