MAORY optomechanical design

The different optical designs that locate the optical elements in the MAORY volume impose a different strategy in the design definition of the optomechanics. Considering the different types of elements in the optical design the optomechanics must satisfy the requirement in terms of stiffness, mass and provide a compensating effect respect to the thermal breathing of the materials. In the paper are presented the solutions taken and the mounts working principle. In particular, the aspects that underline and analysed in the simulation are: 1) The behaviour of the mounts in earthquake condition and in thermal survivor condition that means twenty degrees of variation of temperature 2) The operational condition, the deformation induced in the optical surface due to the gravity, the alignment, and a variation of temperature. 3) The modal analysis of the structure
