Ampair 600 wind turbine three-bladed assembly substructuring using the transmission simulator method

Roettgen, Daniel R.; Mayes, R.L.

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.
