摘要：The reductions of vibrations in structures through the addition of passive systems such as absorbers, custom named TMD (Tuned Mass Damper), have been studied by several authors in recent decades. However it has been more stimulated to study the efficiency of these devices by a model that represents the structure by a one degree of freedom mechanical system. This hypothesis is generally valid, since the natural frequency of the mode to be controlled is sufficiently spaced from the adjacent natural frequencies of the structure. Insofar as the degree of structural complexity increases, this assumption becomes less realistic.
