纵扭型压电超声电机的结构优化

Structure Optimization of Ultrasonic Motor using Longitudinal and Torsional Mode

对纵扭复合型压电超声电机的结构进行了优化 ,包括压电陶瓷片的制作和安放位置、纵振位移振幅和扭振线切变位移振幅的放大 ,并对大直径电机进行了有限元分析 ,认为定子和转子应按振型设计接触面。

In this paper ,the structure of ultrasonic motors using longitudinal and torsional mode is optimized. Firstly, the place of piezoelectric ceramic is optimized,then the displacement amplitude of longitudinal vibration and torsional vibration is magnified, at last, the contact of stator and rotor should be designed according to FEM analysis is indicated.
