Abstract
Travelling wave ultrasonic motors are a new type of small scale actuators. They have been attracting considerable attention in industry because of their unique characteristics such as high torque, low speed, compact size, silence and good controllability. The stator/rotor contact in such motors displays inherently non-linear dynamic characteristics which are most important for understanding and designing the motor performance [1,3]. In this paper two stator/rotor contact models, an analytical model and a finite element model, have been used in the investigation of the dynamic contact problem. As an analytical model, a visco-elastic foundation model was developed, which is capable of predicting the tangential velocity fields and tangential stress distributions of the stator/rotor interface and simulating the stick/slip phenomena in contact areas. The influence of main material and geometrical parameters of the motor and different operating conditions have been investigated. The stator/rotor contact models and the analysis methods presented in this paper provide a general approach for modelling travelling wave ultrasonic motors as well as a design tool for optimizing motor performance with the flexibility of allowing for a wide variety of geometries and materials.
