Abstract

The embodiment of the invention provides a wind power blade torsion test tool and a wind power blade torsion test method. The wind power blade torsion test tool comprises a test board, an annular fixing device and a loading device. The annular fixing device is used for being arranged on the outer side of a testing section of the wind power blade in a sleeving mode in the length direction of the wind power blade, and the loading device is used for pulling the cable to apply traction force to the annular fixing device so that the wind power blade can generate torsion deformation capable of being detected. According to the wind power blade torsion test tool provided by the embodiment of the invention, only the loading device applies the load to the wind power blade in the loading process, no other load causes interference to the wind power blade torsion test tool, and the force direction and the force arm are not changed when the loading device loads the load; therefore, the torque rigidity analyzed by using the tool is more accurate.

Description

technical field [0001] The application belongs to the technical field of wind power blades, and in particular relates to a wind power blade torsion test tool and a wind power blade torsion test method. Background technique [0002] Wind turbine blades are one of the important components of wind turbines to convert wind energy into mechanical energy. The main material is composite materials, and the cost of construction accounts for more than 20% of the cost of the unit. High-power units require a larger swept area of ​​the wind turbine, which means that the size of the wind turbine blades increases, so the wind turbine needs to be matched with large blades accordingly, so that the wind turbine blades are subjected to more and more torsional deformation during use, which is harmful to wind turbines. The torsional nature of the blade presents serious challenges. Precisely designed torsional stiffness of wind turbine blades can avoid blade flutter and improve blade life. The ...
