Abstract

The invention discloses a ground support structure for a high and low temperature environment simulation test system, comprising a bottom heat storage structure, an invar bottom support structure, a heat preservation structure and an invar non-deformation platform; the support structure is divided into four layers from bottom to top, The bottom heat storage structure, the Invar bottom support structure, the thermal insulation structure and the Invar non-deformation platform are in sequence; the bottom heat storage structure includes the foundation pit waterproof coating, the melon seed sheet heat storage layer and the cement mortar leveling layer; the Invar bottom support structure includes Bottom embedded steel plate, Invar rib, Invar steel tube, stainless steel sealing plate at the bottom of the box, stainless steel bellows, Invar mesh rib, Invar mounting flange, stainless steel bottom plate and carbon steel I-beam frame; thermal insulation structure includes Insulation glass brick, pressure steel plate and asbestos plate; Invar non-deformable platform including non-deformation platform and connecting bolts. The whole supporting structure of the present invention has strong load-bearing capacity and high and low temperature resistance, and has good stability, deformation resistance and safety.

Description

technical field [0001] The invention relates to the field of an anti-deformation ground support structure, in particular to a ground support structure for a high and low temperature environment simulation test system. Background technique [0002] With the rapid development of today's science and technology, environmental testing has become an indispensable part of research in many disciplines. In the aerospace field, before a newly developed spacecraft is put into use, it usually undergoes various environmental simulation tests on the ground, especially high and low temperature environmental simulation tests. Through this type of ground test, the rationality of the mechanical structure design of the spacecraft, the performance of materials in different thermal environments, and other deficiencies and hidden dangers in the design can be solved before launch, which can improve the reliability of the equipment. [0003] Since most spacecraft are of large volume and large mass...
