Strategia di ottimizzazione vibroacustica per un gearbox di turbina eolica. Vibroacoustic optimisation strategy for a wind turbine gearbox

This thesis is the result of a collaboration with ZF Wind Power, to investigate the approach to derive a simplified geometry of a state-of-the-art gearbox of a wind turbine, and to optimise this for noise and vibration. The reproduction of the simplified geometry, the computing of the natural frequencies of the full and simplified models and the changes aimed to the optimisation were performed with the FEM software MSC Patran/Nastran Student Edition 2010 (www.mscsoftware.com)
