In order to improve the robustness of conventional dynamic absorbers, we propose the multi dynamic absorber and its optimum design method. Although the design method for single and dual types of dynamic absorbers has already been established, their vibration control effects are very sensitive to changes of parameters such as the natural frequency of the controlled object and the damping coefficient of the absorber itself. The quadruple and sextuple types of dynamic absorbers designed by the proposed method are demonstrated. They are effective in controlling the vibration of the controlled object under changes of these parameters and maintain stable damping performance.
