摘要

在对盘式行波超声电机定子进行三维有限元建模的基础上，研究了定子表面下粘结的几种压电陶瓷对激发超声振动的影响。由于所提出的边界条件，考虑了机电耦合效应，利用ANSYS有限元软件包进行了数值模拟。得到了振动模态、共振频率和电压感应位移。计算结果与实测数据吻合较好。

The influence of piezoceramic actuator on the stator vibrations in traveling wave ultrasonic motor

Based on the 3D finite element modeling of the stator in disc-type traveling wave ultrasonic motor, the influence of several kinds of piezoelectric ceramics bonded underneath the surface of the stator on exciting ultrasonic vibrations was investigated. Taken electromechanical coupling effect into account, numerical simulations were carried out by using the ANSYS finite element software package due to the boundary conditions we proposed. Vibration modes, resonance frequencies and voltage-induced displacements were obtained. The calculated results were in good agreement with the experimental data we measured.
