Item Quality standardization for casting parts of wind power turbines using advanced simulation of the process(Federación de Asociaciones de Ingenieros Industriales de España, 2008-05) Meléndez, Antton; Anglada, EvaThis paper arose from a work on advanced simulation on casting wind powered turbine parts made from high tenacity ductile iron. The technical target was extracted from the Haizelan Project, carried out with Basque Country Foundrymen's Association (Spanish Foundrymen's Federation), two foundries, TS Fundiciones (Zestoa-Guipúzcoa) and Fundiciones Urbina (Urbina-Álava) as process suppliers and Gamesa Eólica (Huarte-Navarra) as part and geometry supplier. The study shows it is now possible to obtain highly accurate predictions in pouring and solidification using microstructure calculations simultaneously, and from then on good predictions about final microstructures and subsequent mechanical properties of castings. All related tasks in simulation were performed using FEM (Finite Elemets Method). Referred to metallographic studies and tests, which were done at Inasmet-Tecnalia laboratories.Item Quality Standardization of Big Size Castings for Wind Power Turbines(ESI Group, 2008-05) Anglada, Eva; Meléndez, AnttonThis paper starts based on an advanced simulation work about casting parts of wind power turbines made in ductile iron of high tenacity. The technical goal was extracted from the a research Project, carried out with Basque Country Foundrymen Association (Spanish Foundrymen Federation), two foundries, TS Fundiciones (Zestoa-Guipúzcoa) and Fundiciones Urbina (Urbina-Álava) as process suppliers and GAMESA Eólica (Huarte-Navarra) as part and geometry supplier. The study shows that nowadays it is already possible to obtain predictions with high accuracy in pouring and solidification simulations using simultaneously microstructure calculations and after these ones good predictions about final microstructures and so the subsequent mechanical properties of the castings. All concerning tasks in simulation have been made using FEM (Finite Elements Method). Referred to metallographic studies and tests, they were made at Inasmet-TECNALIA laboratories.
