Motion Analysis and Simulation of the Stator Driving-Surface of the Cylinder-Sphere Ultrasonic Motor with Multi-Degree of Freedom

The motion suppositions of the stator driving-surface are suggested for the cylinder-sphere ultrasonic motor with multi-degree of freedom. The motion equations of the driving points on the stator are established based on the amplitude of a special driving point. The motions of the driving points are simulated in MATLAB environment. The motion principle and characteristic of the driving points are analyzed. Because the amplitude of the special driving point can be calculated or tested, the motion analysis and simulation method in this paper is quantitative, so it is effective for studying the driving principle, improving the properties and realizing the simulation design of the motor.
