摘　　要：基于矩形薄板面内振动的直线型复合超声波电动机振子的尺寸设计就是通过调整复合振子弹性体的尺寸参数,并借助ANSYS的模态分析,最终在同一驱动频率下激励出弹性基体的两个面内振动模态,从而实现压电振子表面按椭圆轨迹的振动。通过ANSYS分析得到了振子频率随各尺寸参数的变化规律,从而总结出矩形超声波电动机压电振子设计的基本步骤,最后进行了尺寸优化设计分析并进行了对比。结果表明该振子设计的方法可以用于矩形超声波电动机压电振子的尺寸调整问题,从而为实现谐振提供了很好的调整方法。The size of the compound ultrasonic motor vibrator, which based on the in-plane vibration of a rectangular plate, was designed by adjusting the parameters, finally to inspire L-B vibrations modes under the same driving frequency by ANSYS analysis. Through which, the vibrator of ultrasonic motor realized the elliptic orbit vibration. The changing regula- tion of vibrator frequency for different vibrator size parameters of ultrasonic motor was obtained. The basic designing steps of rectangular ultrasonic motor piezoelectric resonators were sunmarized, and the sizes of vibrator were optimized. Results show that the vibrator design procedures can be used for the design of rectangular ultrasonic motor piezoelectric resonators, so as to provide a good method to adjust the sizes of rectangular ultrasonic motor.
