摘要
阐述了超声马达振动模态的分析方法 ,介绍了有限元分析方法在超声马达振动模态分析中的应用 .并以直径为 3 0 m m的行波型超声马达为例 ,给出了振动模态有限元分析步骤和模态分析及谐响应分析结果 ;对制作的电机进行了共振频率测量 .结果表明 :分析结果与实测结果吻合 .
The analysis methods for ultrasonic motor′s vibration mode are expounded in the paper. The usage of finite element analysis method in the vibration mode analysis of ultrasonic motor is also introduced. Taking traveling wave type ultrasonic motor with 30 mm in diameter as an example, the motor′s vibration mode analysis process by using ANSYS is given. Also the results of vibration mode analysis and harmonic response analysis are presented. The fabricated motor′s resonance frequency is tested. The result indicates that the analyzed results are coincident with measured results.
