Abstract

This paper offers an overview of the structural analyses of the MORFEO (formerly known as MAORY [1][2][3]) Main Support Structure (MSS). MORFEO is a first light instrument for ELT (Extremely Large Telescope) that passed, recently, the Preliminary Design Review. The models are validated through FEM Analysis approach, utilizing CAD (Autodesk Inventor) and CAE (Ansys Workbench) software. In order to have a lighter model for the MORFEO MSS, and shorter computational times, simpler FE models than the 3D CAD have been developed. This discretization of reality is a standard approach in the FE analysis and in this paper it is demonstrated that this method provides accurate results at global level. A complete setting of all analyses performed to satisfy the technical requirements and specifications is shown
