Improve the earthquake resistance of the tower. In the design of a wind power hybrid tower, the bottom ring is the part that bears the wind load and needs to have sufficient strength and stiffness to ensure the stability of the tower; the upper ring has relatively less reinforcement, mainly to reduce the lateral deflection of the upper ring. force, thereby reducing the inclination of the tower. This can reduce the tower's self-weight damping and improve the tower's seismic resistance. Therefore, the bottom ring reinforcement of the wind power hybrid tower is small and the top reinforcement is large to improve the earthquake resistance of the tower.
1. Calculate the force on each blade of the wind turbine: It is known that the length of each blade of the Vista wind turbine is 44 meters, the air density is 1.225kg/m3, and the wind speed is 11.4 m/s. According to Bates' formula, the thrust on each blade is F=(1/2)ρV2S power, where ρ is the air density, V is the wind speed, and S is the blade area.
2. Calculate the total force on the wind turbine: The wind turbine has three blades, so the total force is three times the force on a single blade. Fenjiu 3. Calculate the output power of the wind turbine: Knowing the total force of the wind turbine and the transmission ratio of the wind turbine gearbox, the output power of the wind turbine can be calculated.
