In order to control the mechanical vibration of multi-degree of freedom system, this paper proposes the practical application of dynamic absorbers and a new approach for these design. It is widely known that the design method for a dynamic absorber to one degree of freedom system has already been established. However, there still remains a problem how to constitute suitably the dynamic absorbers to the multi-degree of freedom system. The principal point of the design method proposed here is in exactly estimating equivalent masses and these locations on the each vibration mode, after decoupling the vibration system in modal domain. The locations are selected as the settling point of dynamic absorbers, and the masses are used as an essential design parameter. The effectiveness of the design method is demonstrated by controlling the undamped vibration of a three degree of freedom system using three dynamic absorbers.
