摘要： 为了探索和丰富旋转超声波马达的结构，使其满足响应精准且速度快以及控制简便的要求，设计了Y形旋转超声波马达，并对其结构及动态特性进行了分析。Y形旋转超声波马达将3组压电陶瓷片的横向振动复合成驱动足端面对转子的微幅驱动，通过摩擦耦合在惯性作用下推动转子顺时针或逆时针旋转。运用Workbench软件中的Design Exporation组件对Y形旋转超声波马达定子组件的结构尺寸进行了优化设计，提升了定子组件的性能。构建优化后Y形旋转超声波马达定子组件的有限元仿真模型，并通过模态分析获得了定子组件工作所需的固有振型，通过谐响应分析获得了定子组件的幅频特性曲线，通过瞬态分析获得了1个激励周期内定子组件的振动模态，验证了Y形旋转超声波马达的驱动机理。结果表明，Y形旋转超声波马达压电陶瓷片表面施加电压的最佳频率为20 739 Hz，对应的驱动足端面的振幅为6.95 μm。Y形旋转超声波马达结构简单且具有对称性，能效利用率高，对拓宽超声波马达的应用领域有重要参考价值。
Abstract: In order to explore and enrich the structure of rotary ultrasonic motor to meet the requirements of accurate and fast response and simple control, a Y-shaped rotary ultrasonic motor was designed, and its structure and dynamic characteristics were analyzed. The Y-shaped rotary ultrasonic motor combined the transverse vibration of three groups of piezoelectric ceramic plates into a small amplitude drive by the driving foot face to the rotor, and the rotor was driven to rotate clockwise or counterclockwise under the inertia action through friction coupling. The Design Exporation module of Workbench software was used to optimize the structural dimension of the Y-shaped rotary ultrasonic motor stator assembly, so as to improve its performance. The finite element simulation model of the stator assembly of the optimized Y-shaped rotary ultrasonic motor was established. The natural vibration shape required by the stator assembly was obtained through the modal analysis. The amplitude-frequency characteristic curve of the stator assembly was obtained through the harmonic response analysis. The vibration mode of the stator assembly in one excitation cycle was obtained through the transient analysis, which verified the driving mechanism of the Y-shaped rotary ultrasonic motor. The results showed that the optimal frequency of the voltage applied on the surface of piezoelectric ceramic plate of Y-shaped rotary ultrasonic motor was 20 739 Hz, the corresponding amplitude of the driving foot face was 6.95 μm. The Y-shaped rotary ultrasonic motor has a simple and symmetrical structure, and high energy efficiency utilization, which has important reference value for broadening the application field of ultrasonic motors.
