In order to effectively suppress a number of resonance peaks occurring in a machine structure, this paper proposes a new vibration controlling method which combines the modal analysis using the finite element method with a design method of dynamic absorbers enlarged to control the vibration of multi-degree-of-freedom systems. This method is essential in order to determine the optimum mounting position of the dynamic absorbers and the equivalent masses in these positions with the aid of modal analysis. If the equivalent masses are obtained, the established design method can be applied to the design of each dynamic absorber. The effectiveness of the method is demonstrated by suppressing the first five resonance peaks of a rectangular plate using the four optimal designed dynamic absorbers.
