Description

technical field [0001] The invention relates to the field of wind power, in particular to a simulation device for testing the full working conditions of a transmission chain of a wind turbine. Background technique [0002] The wind turbine transmission system includes hubs, main shafts, bearings, gearboxes, generators and other components. The components of the transmission chain of the wind turbine are subjected to complex wind loads, manifested as bending-torsion coupling and the impact effect caused by gap contact; the transmission chain is arranged on the top of a towering tower, and has forward-backward, sideways and pitching motions under external loads Features: Wind turbines often operate in harsh environments such as sandstorms, corrosion, and freezing, and the wind speed and direction have random uncertainties. Therefore, the transmission chain of wind turbines is prone to structural component failures such as component cracks, wear, and pitting corrosion, resulti...
