Finite Element Analysis of Thermo-Stressed States of the Telescope Objective Model for the Lira-B Space Experiment

The thermostressed state of one of the proposed telescope designs was analyzed by means of a finite element model using the ANSYS software package. It is shown that under normal thermal conditions, small temperature variations (within ±1°C) do not cause telescope malfunction. The range of possible t...

Zusammenfassung:The thermostressed state of one of the proposed telescope designs was analyzed by means of a finite element model using the ANSYS software package. It is shown that under normal thermal conditions, small temperature variations (within ±1°C) do not cause telescope malfunction. The range of possible temperature changes that result in the maximum permissible focus shifts and tilts of the axis of the secondary mirror relative to the primary mirror was determined.
