Abstract
The research activity described in this thesis is the result of the collaboration between the University of Naples Federico II and INAF – Astronomical Observatory of Capodimonte (Naples). The purpose of this work is to present the structural design of the Optical Bench for the Adaptive Optics Module for the ELT – Extremely Large Telescope. MAORY (Multi-conjugate Adaptive Optics RelaY) will enable high-angular resolution observations in the near infrared by employing real-time compensation of the wave-front distortions due to atmospheric turbulence and other disturbances, such as wind action, on the telescope. The main purpose of the optical bench is to provide support to the opto-mechanical mountings and subsystems that will be integrated on it. The proposed design is a truss spatial structure with the aim of optimizing the mass of the Main Structure. In particular, a mechanical-structural analysis of a steel optical bench design has been performed. Finally, in order to reduce the overall mass, an alternative design in CFRP (Carbon Fiber Reinforced Polymer) has been analysed.
