Abstract:
In this work, the performance evolution of a traveling wave type rotary ultrasonic motor (TRUM) in a high-rotating environment is studied. The dynamic model of the stator of the TRUM in the centrifugal field is established, and the centrifugal stiffening effect on the stator caused by the centrifugal force is described. Furthermore, the warping deflection of the stator caused by the centrifugal force is analyzed. It is found to change the original contact state and decrease the performance of the TRUM. The contact model between the stator and rotor in the centrifugal field is established. Moreover, the performance model of the TRUM in the centrifugal field is established, and the mechanism and varying trend of the mechanical performance of the TRUM in this condition are analyzed. Finally, the performance test system of the TRUM is set, and the mechanical performance of the TRUM at high angular velocities environment is measured. And the methods to improve the tolerance of the TRUM in the centrifugal field are put forward.
