Abstract
A new piezoelectric cantilever energy harvester based on vortex-induced vibration was proposed. The influence of some parameters was by mathematical modeling, numerical simulation and experimental testing. The results showed that the voltage value increased with the increase of wind speed within the test range. When the bluff body was a cylinder with a diameter of 0.02 m, a height of 0.05 m, and the ratio of the distance between bluff body and harvester and bluff body diameter was 2, the maximum voltage of the T-type piezoelectric cantilever beam energy harvester was 1.02 V. It provided theoretical and experimental references for energy harvesting in the wind.
