Experimental Dynamic Substructuring Coupling and Decoupling- Application to Ampair 600 Wind Turbine-

The need to analyze and optimize the large and complex structures, locally and globally, and have knowledge of local and global dynamic, has induced the notion of Dynamic Substructuring. In the course of time several DS techniques are developed from which some are mainly based on experimental routine. They are known as experimental DS and assemble measured and analytically derived substructures in the frequency domain. In order to advance, compare and classify the experimental DS theory and technology a test bed (Ampair 600 wind turbine) is initiated by the substructuring focus group at the Society for Experimental Mechanics. Based on this idea the Engineering Dynamic workgroup at Delft University of Technology has started his program which runs through couple of iterations before the Ampair 600 is completely analyzed. This thesis concentrates on the first iteration in which attempt is done to combine three blades with the hub. The emphasis is on the Frequency Based Substructuring (FBS) in general and Lagrange Multiplier Frequency Based Substructuring (LM FBS) and experimental modeling techniques in specific
