In this paper the projections made by the slits are called “sub-reeds” for convenience. Though the sub-reeds play important roles in an ultrasonic motor, their dimensions are generally decided through trial and error. This paper presents the optimum design method of a sub-reed by using elastic vibration analysis. This method calculates the dimensions of the sub-reed of which resonant frequency is same as that of the basic disc. This paper also presents that the resonance of the sub-reed mainly causes the magnification of the amplitude by using finite element analysis. The optimum design method and the mechanism of the magnification mentioned above are confirmed by experiments.}, pages = {120--125}, title = {超音波モータにおける副振動片の最適設計}, volume = {57}, year = {1991} }
