Abstrakt: |
The system characteristics and effects of a novel active mass damper are investigated by means of its application for control of wind-induced bridge vibrations. Due to the presence of self-excited forces, stability issues are considered and a stability measure proposed. By virtue of the generation mechanism of the control forces, a superior low power demand of the actuators is achieved in comparison to other proposed mass dampers. The performance of the new damper is studied using a numerical example. |
