| Abstract: | This paper briefly describes the basic principle of travelling wave ultrasonic motor and makes a comparison between the finite element method and the classic vibration theory in analyzing the stator composite annular plate. The natural frequency and vibration mode of the stator annular plate in free conditions are analyzed using finite element, and the results are given. On this basis, the operation principle and process of the annular plate ultrasonic motor are emulated using the obtained data. |
