Finite Element Analysis of the Structural Mechanics of the Telescope Objective for the Lira-B Space Experiment

Abstract

Finite element mathematical models for the real and simplified telescope objectives employed in the Lira-B space experiment are presented. The results of simulation of the mechanics of the objective subjected to various external loads, both static and dynamic, are given. The simulations were performed in ANSYS software. Three methods for simulations characteristics of lightweight parts of the objective are described, two of which are used in the simulations. A comparison of the results obtained using both real and simplified (reduced) models indicates that the simplified model can be used for initial simulations. Moreover, this model with reduced characteristics provides an easier way to generate a finite element mesh and requires significantly shorter computational time.
