Abstract

The calculation model of two types of solid structure and divided structure were prepared, vibration characteristics for the models were calculated by a computer program. In the vibration analysis, FEM was used. On the basis of the numerical simulations, the vibration characteristics were compared. The followings were clarified. (1) As the order of vibration mode becomes higher, the vibration amplitude of the divided structure is lower than that of the solid structure. (2) The displacement and velocity of a frame are decreased by the small spring constant between frame and teeth.
