title = "A comparison of common model updating approaches",
abstract = "In this paper, three common model updating approaches are considered to evaluate their efficiencies for model calibration on a component of an Ampair 600W wind turbine. This turbine is a test bed for the Substructuring Focus Group of the Society of Experimental Mechanics. The fin of the wind turbine is chosen to be investigated in updating procedures. Firstly, model updating method has been developed using an objective function based on extracted eigenfrequencies. The objective function is chosen as a sum of weighted eigenfrequencies with respect to their importance. In the second procedure, weighted Modal Assurance Criteria (MAC) are used to define the objective function. Finally, measured and simulated Frequency Response Functions (FRFs) are directly used to find the best correlated Finite Element (FE) model. The results of three updating procedures are then compared to measured eigenfrequencies, mode shapes and FRFs, and the evaluation of the performance of these three different model updating methods is discussed.",
