摘要
研究了一种采用径向振动的驻波型超声波电机。首先分析了电机的结构,然后利用有限元分析软件ANSYS建立定子有限元模型,基于该模型分析了压电陶瓷的结构尺寸对定子振动特性的影响,进而确定了定子的结构尺寸,并进一步分析了定子的瞬态响应特性。最后根据理论分析结果试制了样机,对样机进行了试验测试,测试结果表明,所设计的电机具有较好的输出性能。
A standing wave type ultrasonic motor working on radial vibration mode is studied.Firstly,the structure of the motor is analyzed.Secondly,a finite element model of the stator is built with finite element analysis software ANSYS.The impacts of piezoelectric ceramic structural parameters on the vibration characteristics of the stator are investigated based on the finite element model.The structural parameters of the stator is determined.Transient response of the stator is further analyzed.Finally,a prototype motor is manufactured according to the theoretical results.Experimental tests are conducted on the prototype motor.The test results show that the designed motor has good output performances.
