双定子单转子超声电机转子结构的优化设计
|
摘要
为了避免超声电机工作时,转子也发生振动,以双定子单转子行波型旋转超声电机为研究对象,建立了该电机转子的参数化有限元模型,运用灵敏度分析的方法,分析了转子的模态频率对各个结构参数的灵敏程度。在此基础上,运用有限元软件ANSYS的结构优化分析工具,对转子进行了优化设计。优化后的转子的模态频率远离了电机定子的工作频率。
In observation of investigating the vibration of the rotor resulted from the running of an ultrasonic motor,an ultrasonic motor with double stators and single rotor was taken as a reference. A parametric finite element model of the rotor of traveling wave ultrasonic motor with double stators and single rotor was built. The sensitivity of rotor's modal frequency to the rotor's structural parameters was calculated based on sensitivity analysis method. ANSYS was further employed for optimization design of the rotor in terms of sensitivity analysis. Results demonstrate that optimization design of the rotor is effective in keeping the modal frequency of rotor out of the working frequency of ultrasonic motor.
