Abstract

The authors have proposed the single-tuning viscous mass damper system based on fixed points theory. Vibration control effects of single-tuning type system are very sensitive to changes of parameters such as the natural frequency of the controlled object and the damping coefficient of the absorber itself. In this paper, response control method using multi-tuning type system with diversified natural frequencies is proposed. It is shown that the multi-tuning type system proposed herein is considerably effective in improving the reduction efficiency of the response magnification factor than single-tuning type system.
