摘要：

Based on a contact model of traveling wave ultrasonic motor with visco-elastic contact layer on stator surface, effects of thickness of frictional material and its modulus of elasticity on characteristic of the motor are simulated using MATLAB method. The results show that, the thinner the thickness, and the higher the modulus of elasticity, the better the motor characteristics. The interface conversion efficiency is higher when thickness is smaller than 0.5 mm and load torque is greater than 36 N·mm; It has a maximum when thickness is about 0.2 mm. As a result, it is more suitable to choose 0.2 mm for the thickness of the material. When modulus of elasticity is higher than about 1.5 GPa, the interface conversion efficiency is higher in the greater range of load torque, so the motor has better driving capacity. These results have certain theory directive significance to the choice of the frictional material. This model is compared with the compliant slider and rigid stator model. The results show that, the motor based on this model will gain bigger output torque.
