Abstract
A design method of a dynamic damper by using the substructure synthesis is presented in this paper. For the purpose to reduce vibration of a stator in an electrical rotating machinery caused by the electro-magnetic fields, we adopted a method to predict effects of the dynamic damper from synthesizing the mathematical frequency response function of the dynamic damper and the experimental frequency response functions obtained from actual structure. And we derived the equations for the design of a dynamic damper's mass and stiffness by the experimental frequency response function of the structure, and we confirmed that this method has practical accuracy through an experimental evaluation on a cylindrical structure.
