Ampair 600 wind turbine three-bladed assembly substructuring using the transmission simulator method
This paper contains an example of the transmission simulator method for experimental dynamic substructuring using the Ampair 600Wind Turbine. The structure of interest is the hub-and-three-bladed assembly. A single blade and hub is used as a substructure to develop a model for the hub-and-three-bladed assembly. The single-blade-and-hub substructure was developed from elastic modes of a free-free test and rigid body modes analytically derived from measured mass properties. This substructure can be rotated and replicated using the hub as a transmission simulator. Substructuring calculations were then performed using the transmission simulator method to derive a model of the hub-and-three-bladed assembly. This paper concludes with a comparison for this combined model to truth data derived from a free-free modal test of the entire rotor.
