摘要

基于有限元法建立了杆式超声电机定子机电耦合动力学模型。利用该模型对定子的动力学特性进行了分析,理论结果与样机定子的实验结果吻合较好。讨论了定子的结构设计原则和满足定子模态要求的方法。基于模式搜索算法,建立了满足设计要求的最优模型。数值仿真结果表明,该优化模型对定子的结构设计是有效的。

An efficient approach to optimize the vibration mode of ultrasonic motors
The electromechanical coupled dynamic model of the stator of the bar-type ultrasonic motor is derived based on the finite element method. The dynamical behavior of the stator is analyzed via this model and the theoretical result agrees with the experimental result of the stator of the prototype motor very well. Both the structural design principles and the approaches to meet the requirements for the mode of the stator are discussed. Based on the pattern search algorithm, an optimal model to meet the design requirements is established. The numerical simulation results show that this optimal model is effective for the structural design of the stator.
