Abstract
In this study, a new method that combines the tuned liquid column damper (TLCD) and the Savonius type hydrokinetic turbine (STHT) is proposed to harvest energy from mechanical vibrations of structures in a green power production way. The proposed approach converts hydrokinetic energy into electrical energy during the vibration control process. Excessive shaking table tests are performed to investigate the starting performance and energy conversion efficiency. An optimized circuit configuration is revealed for power maximization. The impact of STHT on the dynamic characteristics of TLCD is elaborated. In addition, a parallel circuit that allows both charging of energy storage components and vibration control is illustrated and experimentally verified. The results demonstrate the feasibility and characteristics of the approach in energy harvesting.
