Background
In large-scale wind-powered electricity generation serial products, the connection of the rotor wing strand and the fan blade is not easy to realize. At present, a T-shaped bolt mode is generally adopted for connection, and holes are uniformly drilled in a blade root shell along the radial direction of a blade root cylinder through sawing the blade root end face and setting the position away from the blade root end face, and the stud bolts can be axially embedded into composite disassembly materials of the blade end face and connected with transverse nuts penetrating through the blade shell along the radial direction. This connection is unavoidable in that stress concentrations occur at the root of the blade, so that a great demand is placed on the strength of the root connection. For large-size blades, the traditional T-shaped bolt connection mode can not meet the requirements of the ultimate strength and the fatigue strength of the blade.
