چکیده انگلیسی
A novel single-mode linear piezoelectric ultrasonic motor based on asymmetric structure is proposed. The motor adopts the combination of the first longitudinal vibration and the asymmetric mechanical structure to produce the oblique movement on the driving foot; then, the linear output motion is obtained under the friction coupling between the driving foot and the runner. The motor is designed and its operation principle is illustrated in detail. The transient analysis is developed to verify the formed movement on the driving foot. A prototype is manufactured and its vibration characteristics are measured by a scanning laser Doppler vibrometer. An experimental system is established and the output performances of the motor are tested and discussed. The results indicate that the maximal no-load velocity of the motor is about 127.31â¯mm/s under the voltage of 150 Vp-p and the preload of 30â¯N. The maximum thrust force is about 2.8â¯N when the voltage and preload are 150 Vp-p and 40â¯N. The related works in this paper has verified the feasibility of the proposed single-mode ultrasonic motor based on asymmetric structure.
