| Abstract: | According to the GL standards, the finite element method is used to analyze the extreme strength of the hub of a MW class wind turbine generator system. The S N curve of the hub is modified and the fatigue load cases are analyzed for fatigue calculation, and the load time series for fatigue calculation are simulated by GH Bladed software. The fatigue life of the hub is calculated by ANSYS/nCode software, and the results show that both the extreme strength and fatigue strength of the hub can meet the design requirements. The analysis results can provide reference for the design of the hub of MW class wind turbine generator system. |
