Research on strength calculation methods of rotor hub of HAWTs

Journal Article


Abstract


  • The aerodynamic characteristic of megawatt wind turbine was calculated by applying the blade element momentum(BEM) theory, thus the dynamic ultimate load of the hub and the dynamic load of the blade root were obtained. According to the structure and characteristic of the hub, and applying the finite element analysis(FEA), the static strength analysis methods were studied for the rotor hub of horizontal axis wind turbines(HAWTs). And a strength analysis method of bolts which connect the blade and hub was intructed. As an example, the ultimate loads of the rotor hub of a MW HAWTs in different ultimate conditions, and the strength analysis of the rotor hub are proposed. The strength analysis methods of rotor hub with more practical value in engineering application are achieved.
