Equation of motion of the dynamic vibration absorber for large-scale low frequency structures proposed previously is derived for the case with dual auxiliary systems and the numerical method of design of the quasi-optimal tuning and damping conditions of the dual case is presented. And it is verified by the simulation that the vibration suppression effects are improved in comparison with the single case. Then, applying to the three-degree-of freedom system with the fundamental frequency of 0.1 Hz, the superiority of the present method to the conventional design concept is shown in the low frequency range. Finally, the prototype of the present dual dynamic vibration absorber was manufactured to apply to the one-degree-of-freedom system with the natural frequency of 0.69hz and the vibration suppression effects were actually ascertained through the experiments of the free vibration and frequency response.
