摘　　要：为满足圆柱弯曲型超声电机定子的结构设计要求和改善现有的设计方法,该文采用参数化设计语言ADPL自编制的优化设计程序对定子结构进行了优化,并制作出定子直径30mm、长34mm的圆柱弯曲型超声电机原型机。优化计算与实测结果表明,压电陶瓷片的中心位置十分接近于定子弯曲振型的波谷中心,定子驱动端与末端振幅比值的计算值与实测值基本吻合。In order to satisfy the demands for the stator structural design of cylindrical ultrasonic motor with bending vibration modes and improve the design methods at present, an optimization program of the stator structure based on the parameterized language APDL was established and the stator structure was optimized in this paper. A prototype of cylindrical ultrasonic motor with bending vibration modes was designed and manufactured using the optimal parameters. The stator has a diameter of 30 mm and a length of 34 mm. The optimized computation and the experiment results indicated that the central position of the piezoelectrical ceramic plate was very near to the center of the wave hollow of the bending vibration of the stator, and the measured value of the amplitude ratio of the stator was well consistent with that obtained by the optimal design program.
