Abstract

This paper proposes a dual-function electromagnetic (EM) damper, which simultaneously provides vibration damping and electrical power. A discontinuous conduction mode (DCM) buck-boost converter is utilized as the energy harvesting circuit due to its resistive feature, which enables the optimization of energy harvesting efficiency and vibration damping performance. This paper also presents a numerical study on its application in a full-scale bridge stay cable considering along-wind excitations. The numerical results reveal that the dual-function EM damper achieves a comparable vibration control performance as the optimal viscous damper in a broad wind speed range. Also, average output power of 82.5 mW to 2396.8 mW is harvested with high efficiencies in the wind speed range from 9m/s to 15m/s.
