| Abstract: | In this paper, the effect of adhesive on the vibration of the stator in ultrasonic motors was investigated in details. The analysis was based on the finite element model for the vibration of ring type travelling wave ultrasonic motors. Calculating the mechanical electrical coupling effect in piezoelectric ceramics, the relation between the thickness, characteristics of adhesive and the trajectory of the particle motion on the surface of the stator was revealed. The requirement of characteristic and the thickness scope of adhesive were determined. Also, the failure of ultrasonic motors due to the adhesive bonds was discussed and several technical suggestion and notes through the processing procedure were presented. It is indicated that the calculation model and analysis in this paper were accurate and effective. |
