Abstract of the presentation
The work “Development of a digital twin for predictive maintenance of the structure of floating wind turbines” presents a methodology for the development of a structural digital twin, conceived for its application in the predictive maintenance of floating wind turbines. The digital twin is based on a detailed three-dimensional dynamic FEM (Finite Element Method) model of the structure coupled with a time-domain seakeeping analysis solver. The resulting model has several million degrees of freedom, making it unmanageable for operational use.
For this reason, Model Order Reduction techniques (MOR) are used in order to generate a reduced model with a few hundred degrees of freedom and high precision. The techniques used for this are the SVD (Singular Value Decomposition) method and the EMOR (Enriched Modal Matrix Reduction) method developed by the authors.
