| 摘 要： | 在微机电领域中，为获得超声波电机的振动模态及谐响应特性，利用SAMCEF有限元分析软件对直径为50 mm的环形行波型超声波电机压电转换器和定子的振动状态进行了分析；在完成超声波电机定子建模的基础上，进行振动模态分析和最优模态选择，并在此基础上进行了谐响应分析。分析结果表明，利用SAMCEF软件对超声波电机进行分析被证明是一种行之有效的方法。

| Abstract: | Aiming at obtaining the ultrasonic motor vibration mode and harmonic response characteristics,SAMCEF finite element method（FEM）software was used to analyze stator vibration state of a ring-type traveling wave ultrasonic motor with 50mm in diameter.Based on modeling of the ultrasonic motor stator vibration mode was analyzed and optimum vibration mode was selected,and harmonic analysis was analyzed near the optimum vibration mode.The results indicate that SAMCEF is an effective method in the ultrasonic motor analysis. |
