Abstract


The paper presents results of finite-element modeling and the analysis of temperature fields on the RT-70 radio telescope main reflector arising from the influence of solar heat. The worldwide experience of the design and creation of unique constructions is analyzed and the mechanical problems of the full-circle radio telescope RT-70 are classified. The finite-element thermal analysis of the RT-70 is chosen as the primary problem to solve. Mathematical and 3D finite-element models are developed to analyze the temperature fields in the RT-70 main reflector. These models allow estimating, with high validity, temperature values in various points of the main reflector in different climate conditions and different times of day.
