摘要
以矩形复合平板为对象，根据弹性薄板理论，确定复合板的等效弹性常数，导出复合平板的弯曲振动方程；并利用表观弹性法，建立了振子共振频率的简单解析表达式。由于计算方法简单。
This paper describes a computer control system for piezoelectric traveling wave motor. The experimental results show that under the instruction ordered by the software, the piezoelectric traveling wave motor can be operated with any step program of angle/time, in which the step angles vary from 0.15° to any values, and a high angular resolution is obtained.
