Abstract

The goal of this study is to validate the finite element model of a wind turbine blade based on the results from a test bench. The finite element model, its design discrepancies and the simulated experimental setup are explained. The design and tests were performed in the projects SmartBlades and SmartBlades 2. The following analyses have been carried out for verification purposes. - Flapwise and edgewise extreme bending tests and comparison with global displacement and local strain measurements. There were four bending tests in total - Torsion tests and comparison with global displacement and local strain measurements. There were three torsion tests in total The compared data is analyzed. The effect of variations in load introduction and boundary conditions are studied. Eventually, the wind turbine blade and all data from the load case scenarios are published for further use
