Load Simulation Analysis of 1.5 MW Horizontal Axis Wind Turbine

Wind turbine blades are subjected to a variety of loads in actual operation, which are prone to deformation and cause the strain and stress concentration of the blade structure, thereby affecting the safe operation of the wind turbine and the service life of the blade. Therefore, a numerical simulation study on the coupling of wind turbine blade loads with their displacement, deformation, and stress is carried out. The results show that at the same wind speed, as the wind turbine speed increases, the pressure on the windward side of the blade increases, the negative pressure on the leeward side decreases, the pressure difference between the two sides increases, and the maximum pressure is distributed in the tip of the blade; the blade is under different loads, among which the aerodynamic load is the main factor affecting blade deformation and stress generation. The maximum deformation of the blade appears in the direction of the swing.
