Modeling of Load Distribution in Large-Size Wind Turbine Blade Bearings
This paper proposes a procedure for obtaining the load distribution in a four point contact wind turbine blade bearing considering the effect of the structure’s elasticity. The uneven stiffness of the rings and the supporting structures creates a variation with respect to the results obtained with a rigid model. It is necessary to evaluate the effect of the elasticity on the increase in the contact forces in order to be able to design the wind turbine blade bearing and the structures involved in the connection. A finite element model (FEM) has been created for the global model, having also represented the rolling elements and their contact with the raceways. The results obtained using the FEM have been compared with the traditional Hertz contact results.
