[Abstract]:Ultrasonic motor is a new type of motor. Its principle is to use the inverse piezoelectric effect of piezoelectric ceramics to make the stator vibrate through the action of excitation voltage, and then through the friction between stator and rotor to realize the conversion of electric energy to mechanical energy. Cause the rotor to produce a directional rotation. It has the advantages of simple structure, low speed and large torque, fast response speed and no interference from magnetic field. In industrial control, car appliances, computers, intelligent robots and aerospace has a wide range of applications. In this paper, based on the double stator rotary traveling wave ultrasonic motor developed by our laboratory, the finite element contact model of stator and rotor is established, and the radial slip phenomenon, velocity and output torque of the motor are studied by the finite element analysis method. The specific contents are as follows: firstly, the working principle, structural characteristics and application of rotary traveling wave ultrasonic motor are introduced systematically. The research status of double stator rotating traveling wave ultrasonic motor, stator and rotor contact model is reviewed. Secondly, the operating mechanism of rotary traveling wave ultrasonic motor with double stator is discussed, and the inverse piezoelectric effect, piezoelectric parameters, piezoelectric equation and vibration mode of piezoelectric ceramics are introduced systematically. Thirdly, taking the stator of ultrasonic motor with diameter of 60mm as the research object, the modal analysis, harmonic response analysis and transient analysis of the stator are carried out by using the finite element software ANSYS10.0, and the frequency and mode shape of the stator under vibration state are obtained. Amplitude and frequency characteristics and motor startup characteristics. Finally, the finite element contact model of stator and rotor of double stator rotating traveling wave ultrasonic motor is established, and the influence of traveling wave with different phase on radial slip phenomenon is analyzed, and the flexible design of motor rotor is carried out. In order to reflect the advantages of flexible rotor, the characteristics of torque and speed of motor are compared with that of rigid rotor, and the performance of ultrasonic motor is compared with that of traditional ultrasonic motor. The simulation results show that the torque performance of double stator rotary traveling wave ultrasonic motor is greatly improved.
