摘要
因超磁致伸缩材料(GMM)具有应变值大、能量密度高、磁机耦合系数大、响应速度快等优异特性,GMM得到了广泛应用。在分析GMM性能特点基础上,提出了旋转马达的新型工作原理:以GMM为核心驱动元件,设计SHELL柔性机构放大微位移,通过特殊机构驱使定子产生圆周平动,依靠转子与定子间的摩擦力推动马达旋转。最后构造出新型马达的3D模型,并结合有限元软件ANSYS对马达模型进行仿真。
On the basis of analysis of the characteristics of GMM, a new principle of rotary motor is introduced： Terfenol-D （Tb0. 3Dy0. 7Fe1. 9 ） material is used to drive the ＂SHELL＂ flexible configuration, Which can scale the microdisplacement. A special designed mechanism is used to combine 2 GMM actuators to form a pure rotation movement and this movement is used to drive the rotor of motor. Finally, 3D prototype of this research is constructed, and the analysis of motor prototype based on FEM is realized by using ANSYS 8.1.
