Embodiment 1

[0049] When installing the wind turbine blade fatigue test loading device based on the closed-loop self-feedback control system provided in this embodiment, firstly, the upper follower 10 preset to be clamped on the upper side of the blade is bonded to the inner surface of the upper splint 8 as a whole, Bond the lower follower 11 preset to be clamped on the lower side of the blade with the inner surface of the lower splint 9, or use anchorage or other connection methods; then, use a crane to place the upper splint 8 and the lower splint 9 respectively Outside the upper and lower sides of the blade loading section, the upper and lower fittings 10 and 11 can be closely attached to the upper and lower sides of the blade; finally, four sets of connecting bolts are used to connect the upper splint 8 and the lower The clamping plate 9 is fixed outside the position of the loading section of the blade, thereby completing the blade clamping process.

[0050] After the blade clamping pr...

Abstract

The invention provides a wind turbine blade fatigue test loading device based on a closed-loop self feedback control system, which comprises a blade clamp and a dual-drive loading device, wherein thedual-drive loading device is connected with the blade clamp; the blade clamp is used for clamping a wind turbine blade; the dual-drive loading device carries out speed closed loop control through theclosed-loop self feedback control system and is used for generating eccentric mass excitation to drive the wind turbine blade to perform reciprocating vibration along a wave direction. According to the wind turbine blade fatigue test loading device based on the closed-loop self feedback control system, the dual-drive loading device carries out speed closed loop control through the closed-loop selffeedback control system, the dual-drive loading device is adopted to output a large excitation force, the problem of a large excitation force of the fatigue test in the blade wave direction can thusbe solved, and the test load requirements are met.

Description

technical field [0001] The present invention relates to the technical field of wind turbine blade structural testing, and more specifically, to a loading device for wind turbine blade fatigue tests based on a closed-loop self-feedback control system. Background technique [0002] Wind rotor blades are the key components of wind turbines. During the operation of wind turbines, the blades must bear large wind loads for a long time. Whether the blades can work safely within the design fatigue life is very important. The blade fatigue test is an important test in the blade design, shaping, and production process. Through the test, the 20-year operating life of the blade can be simulated, and the structure, layering and bonding design of the blade can be checked. It can also be found that the blade is in the manufacturing process. Some production defects in the blade, verify whether the design and manufacture of the blade meet the requirements. [0003] At present, the excitatio...
