摘要

Test as well as calibration precision of a coordinator is determined by the precision of the test turntable, and the improvement of the test turntable is the most effective way to improve the calibration accuracy of the coordinator. Therefore, it is of great practical significance and value to study a test calibration turntable which is suitable for a certain type of indexer. Based on the working principle of the ultrasonic motor, the mathematical model of the friction coupling interface is established; steady-state output force of the ultrasonic motor and the maximum angular velocity of the rotor are calculated; effect of the friction material type, magnitude of the pre-tightening force, and the rotor angular speed are analyzed on the maximum output force of the ultrasonic motor. The driving performance of the rotary table ultrasonic motor and the start/stop characteristic of the rotary table are studied. Finally, the driving ability of the ultrasonic motor is optimized and verified by experiments.
