Description

technical field [0001] The invention relates to the field of satellite structure testing, in particular to a high and low temperature thermal deformation comprehensive testing system. Background technique [0002] Structural thermal deformation is one of the important factors affecting the positioning accuracy and attitude stability of remote sensing satellites. The adaptive support structure of the satellite payload needs to meet the high thermal stability requirements of on-orbit deformation. In the ground development stage, it is necessary to design, predict and control the on-orbit deformation of the satellite structure. On the basis of accurate thermal deformation simulation, conduct structural thermal deformation tests to predict and control the on-orbit deformation of the satellite structure to ensure high precision of the satellite structure. Realization of thermal deformation control index. [0003] The thermal deformation test of satellite structure needs to simul...
