主动多重调谐质量阻尼器

论文简介：

By resorting to Fourier transform, the equations of motion for the soil-asymmetric structure-active
multiple-tuned mass dampers (AMTMD) interaction system are developed in the frequency domain under
the ground acceleration. The criterion for searching the optimum parameters of the AMTMD is selected as
the minimization of the minimum values of the maximum displacement dynamic magnification factors
(DMF) of the asymmetric structure with the AMTMD. The estimation criterion of the effectiveness of the
AMTMD is chosen as the ratio of the minimization of the minimum values of the maximum displacement
DMF of the asymmetric structure with the AMTMD to the maximum displacement DMF of the
asymmetric structure without the AMTMD. Employing these two criteria, the parametric studies for the
influences of the normalized eccentricity ratio (NER), torsional to translational frequency ratio (TTFR),
stiffness ratio of the soil relative to the structure.
