Design and Experiment of the Ultrasonic Motor to Detect the Edge of Bamboo

【Objective】 In order to detect the tiny defects of the edges of the bamboo slices,micro amplitude vibration of ultrasonic motor was utilized. The relationships between the micro amplitude vibration parameters of the ultrasonic motor and the size of the bamboo slices were studied. The device was designed to detect the change of the edge size of bamboo slices within 100 microns. It provides the theoretical basis for the on-line rapid detection of the production process. 【Method】Using the converse piezoelectric effect of piezoelectric ceramics,elliptical motion in the stator of an ultrasonic motor drives the bamboo movement. The driving point is the edge of the bamboo slices. Under the normal pressure,sliding friction and wave number of different ultrasonic motors with fixed driving frequency of ultrasonic motor,analysis of the motion velocity of bamboo slices and the motion of the stator particle of the ultrasonic motor was analyzed by the stator kinetic equation. The movement of bamboo slices was analyzed by m
