Abstract

This article builds a finite element thermal model of a spacecraft in low-Earth orbit, applies the equivalent steady-state infrared heat flow to simulate the on-orbit thermal environment, and obtains the spacecraft temperature field and thermal deformation field. The analysis results show that the finite element modeling method adopted in this paper can well simulate and analyze the thermal deformation test based on the absorbed heat flow, and provide an important reference for the design and test of the spacecraft.
