Some ultrasonic friction motors uses resonance frequency of two modes to generate ellipse motion on contact point. However there are no detail reports about degree of freedom or constraints on design or tuning of frequency when resonance frequencies in two directions are used. The paper investigates experimentally what phenomena occur when two modes resonance frequency of a vibration mechanism are matched and the mechanism is excited in two directions simultaneously. An experimental vibration mechanism which has the same structure in two orthogonal directions are manufactured and driven under some different driving conditions! e.g. frequency, amplitude or phase of sinusoidal excitation. Then some interesting results such as every driving condition gives influence on resulting vibration status are obtained.
