Abstract

This work will demonstrate structural optimization of large offshore wind turbine blades. Offset in taken in a state-of-the-art commercial wind turbine blade, and the objective is to minimize its mass under critical structural and manufacturing criteria. Finite element models of the root-to-max-chord segment are built taking blade geometry, material layup and loads as input. It is chosen only to model this segment, as the majority of material is placed here. As such, the size of the analysis model is reduced for optimization. The finite element models will demonstrate optimization with both shell and solid-shell elements as well as combinations hereof. The structure is parametrized with layer thicknesses as design variables, which are assigned to patches to reduce the number of design variables. This paper will show preliminary analysis results, and the optimization results will be presented at the conference.
