Abstract

We suggest a new passive type vibration control system, tuned rotary-mass damper (TRMD), which consists of the rolling mass (rotary-mass) and the container (outer shell) allowing the free movement of the mass along its inner arc. This TRMD has a simple construction and is applicable to the structure. The tuning of TRMD can be made by adjusting the diameter of the rotary-mass and the curvature of inside the outer shell. To determine the optimum tuning and damping ratio for a linear system of TRMD, a design technique of tuned mass damper is applied. The frequency response analysis is also performed to the nonlinear system of TRMD. It was found that the response magnification factor of the structure-TRMD system showed a strong dependency on the external strength ratio, and can be reduced by designing TRMD against the targeted external strength ratio.
