摘要
利用有限元法对具有梳状齿的环形压电振子进行了计算，分析了行波马达不同结构参数对压电振子动态特性的影响，绘制了各参数对压电振子固有频率的影响曲线，进行了马达试验，分析结果与试验结果基本符合，可作为这种振子设计的依据。
Ring-type piezoelectric vibrator with comb teeth is calculated by FEM. The influence of different structure parameters on dynamic characteristics of piezoelectric vibrator is analyzed, and the natural frequency curve is given. The motor with this type of vibrator is tested. The results of experiment are in accord with that of FEM analysis,so that can be taken as the basis for the vibrator desigu.
