摘要：

Aimed at the wind-induced response and vibration reduction of an H-rotor type three-bladed vertical axis wind turbine (VAWT), and based on computational fluid dynamics (CFD) method, a numerical simulation is conducted to obtain the blade wind pressure distribution during the rotation period. Then, the wind pressure obtained is applied to the surface of the blades to analyze the wind vibration response of the VAWT. Dampers are arranged at different positions of the VAWT to simulate the vibration reduction capacity. The results show that applying the damper at the connection between the main shaft and the support rod of VAWT could reduce the displacement response of the structure to a certain extent and the maximum drop would reach 44%. Furthermore, the displacement reduction rate of the structure is related to the position of the damper. If a damper is arranged near the top end of the blade, the maximum displacement of the structure would occur at the bottom of the blade. However, if a damper is arranged near the bottom end of the blade, the maximum displacement of the structure would occur at the top of the blade and the maximum drop would reach 40.7%. The results would provide technical reference for research on the vibration reduction of VAWT structures. © 2021, Shanghai Jiao Tong University Press. All right reserved.
