Abstract: Based on the FEM, the properties of the vibrator and the shaft in new ultrasonic vibration internal grinding system were studied in this paper. The design method of new ultrasonic vibration internal grinding (UVG) system by using rotary non-contact transmission device was proposed according to the influence of the sleeve length and thickness to ultrasonic vibration shaft. Experiments about the vibrator,the shaft and the ultrasonic vibration internal grinding system were studied by using PSV-400 Laser scanning vibrometer, and the consistency between the new ultrasonic vibration internal grinding prototype and theoretical design was confirmed.
