dc.description.abstract-translatedThis paper presents finite element model updating of composite part of hybrid discs used in a carousel of an indexing gearbox based on experimental modal analysis. Two geometries, a full disc and a disc with a central opening for shaft insert, manufactured from short glass fibre reinforced epoxy, were investigated. Natural frequencies obtained experimentally were compared with idealized and modified FE models with material defined at the constituent level. By incorporating measured fibre volume fraction, porosity, and local fibre orientation, the modified model achieved an average deviation of approximately 5 %. The results confirm the suitability of the proposed approach for reliable prediction of dynamic behaviour.en
