Experimental study on friction braking deceleration system based on ultrasonic motor

Abstract

In this paper, a set of friction braking deceleration system is designed based on the ultrasonic motor. Because of the fast response and high accuracy, the system can realize the fast and accurate change of the speed, and achieve the stepless control of the speed. First, the structure of the friction braking deceleration system is designed, and the speed of a rotating disk is precisely controlled by the ultrasonic motor. Then, the mechanical model of the system is established, and the effects of various variables on the speed of the system are analyzed. Finally, the maximum braking moment and braking stroke are obtained by experiments.
