Abstract

The integrated FE modeling technique allows to combine different FE models, provided by multiple players potentially located all over the world and who follow their own development and philosophy, within a single large model, properly defined “integrated”, useful for the evaluation of particularly relevant aspects of whole system. The development context of this work is, essentially, the ESO environment for ELT class of Instrumentation. The following paper presents the case study of the MORFEO Calibration Units selector, a very good example of a complex subsystem that integrates other complex subsystems inside the MORFEO MSS (Main Support Structure). This integrated FE modeling work was developed in INAF - Observatory of Naples, in the ANSYS Workbench software platform, exploiting the characteristics of this tool. In order to estimate the real behavior of the CU Selector sub-assembly and its related payload a setting of the integrated analyses has been performed. In this particular case the payloads of the CU Selector are represented by the MCA (MICADO Calibration Assembly) and the FMCU (MAORY Folding Mirror Calibration Unit). They are simulated implementing the FE models provided by MPIA (Max Planck Institute for Astronomy) for MCA and by PF0 WP (INAF - Milano) for FMCU. Also an updated version of CU selector FE model, developed in INAF - Naples, is implemented in the integrated model. The nomenclature and materials, recalled in the following paper, mostly refer to the ANSYS Workbench software.
