Description
technical field [0001] The invention relates to the technical field of thermal testing of satellite structures, in particular to a testing system and method for simulating thermal deformation of composite material rods in a space environment. Background technique [0002] The main working environment of the satellite is the space outside the earth's atmosphere. After the satellite enters the orbit, it needs to work effectively for a long time. The heat exchange between it and the space environment mainly depends on radiation. The surface of the sun faces a cold environment of 3K. [0003] Thermal load is the main load in the space environment. The spacecraft in orbit is subjected to large changes in high and low temperature, and there is a large temperature gradient in the structure, which will cause thermal stress and thermal deformation, which will cause the structure to deform and even vibrate. , the deployable optical equipment and antenna structure on the spacecraft is...
