摘要
为了探索和快速实现多自由度超声电机的设计及应用,提出一种锥型结构的多自由度超声电机。该电机定子采用单足驱动方式,利用四分区的叠层压电陶瓷作为激励元件,分析其产生两维直线运动的驱动机理。利用有限元软件ANSYS对电机建立参数化模型,并导入到多学科优化软件Optimus中进行全局优化求解。优化结果表明,电机多个设计目标都得以实现,最后制作实验样机并成功应用在x-y平台上。
A cone-shaped MDOF-USM(multi-degree-of-freedom ultrasonic motor)is designed for research and application.The single-foot drive mode is adopted on the stator.A four-quadrant piezoelectric stack is employed as the exciting element to generate two-dimensional linear motion,and its movement mechanism is analyzed.The parametric model of the MDOF-USM is set up in ANSYS,and the finite element model is imported into the Optimus(a multi-disciplinary optimization software).Optimization results indicate that the design requirements of the MDOF-USM are fulfilled.Finally,a MDOF-USM is successfully manufactured and applied to an x-y platform.
