Abstract

Taking the key components of the umbrella wind turbine regulating mechanism as the research object, the main stress concentration parts were determined by numerical simulation, and the strength of the key components was checked. Through the wind tunnel test, the variation of the stress on the key components of the adjustment mechanism with the shrinkage angle of the umbrella wind turbine under the actual operating conditions was tested. The results show that the stress on the connecting rod and the small hub increases first and then decreased with the increase of the shrinkage angle, and both reach the maximum stress under the working condition of 45°. The stress of the large hub decreased with the increase of the shrinkage angle. The safety and reliability of the power regulating mechanism of the umbrella wind turbine was verified by numerical simulation and wind tunnel test, which laid a research foundation for the subsequent structural optimization and improvement of the umbrella wind turbine.
