Problems solved by technology

In order to ensure the reliability of the spacecraft and its load during operation, each component sample needs to undergo a space environment thermal test. If the existing large-scale space environment simulation equipment is adopted, a lot of test time will be wasted, and it will also greatly increase test cost
Therefore, the existing environmental simulation equipment needs to be improved urgently

Description

technical field [0001] The present disclosure generally relates to the technical field of aviation and aerospace environment simulation detection tests, and specifically relates to an integrated environment simulation test device and method. Background technique [0002] During the development and service of the spacecraft, various types of space environment simulation tests must be carried out to fully expose the potential defects of the product and test the design and manufacturing quality of the spacecraft. [0003] In order to adapt to the harsh space thermal environment during orbital operation, the reliability of its components needs to be verified and evaluated through space environmental thermal tests. In order to ensure the reliability of the spacecraft and its load during operation, each component sample needs to undergo a space environment thermal test. If the existing large-scale space environment simulation equipment is adopted, a lot of test time will be wasted...
