| 摘 要： | 为了有效提高贴片式环形行波超声电机的机械输出性能，利于超声电机的小型化和微型化，研制了一种贴片式纵弯复合激励圆筒超声电机，电机利用d33工作模式和d31工作模式，由单臂变幅杆和一个环形换能器构成，且变幅杆和换能器采用一体结构．在对电机的工作原理进行分析的基础上，利用ANSYS软件完成了电机的设计和仿真，实现了两个振动模态的特征频率简并，并采用多普勒激光测振仪对样机进行了振动测试，测试结果与仿真结果基本一致．样机的机械输出特性测试表明，样机的最大转速为268r／rain，最大输出力矩为1．1N·m．

| Abstract: | In order to improve the mechanical performance of ultrasonic motor with path annular traveling wave, a miniature patch longitudinal bending composite excitation cylindrical ultrasonic motor is proposed. Ultra- sonic motor is proposed based on the advantages of working mode of d31 and d33. The proposed motor contains sin- gle arm amplitude transformer and an annular transducer, and with integrated structure. The working principle of motor is introduced, ANSYS is adopted to accomplish the design and simulation, and the resonance frequencies of the two vibration modes of the motor are tuned to get close to each other. Vibration tests of＇ prototype by a scanning laser Doppler vibrometer eoncide with simulation results well, and the maxium rotational speed attains 268r/min and the maximum output moments 1.1 N ~ m. |
