Abstract

The European Southern Observatory (ESO) is managing the Extremely Large Telescope (ELT) system performance and budgets. The Telescope Main Structure, Hosted Optical Units and Scientific Instruments are designed and built outside ESO by contractors and consortia. Within this scope, system simulations are performed including the coupling between the Telescope Main Structure and its Hosted Units. Both dynamic couplings relevant for control-structure interaction, seismic loads, and micro-vibrations as well as quasi-static deflections are included in these simulations. This paper explains the modeling approach and the first simulation results.
