摘要
Abstract
The infrared heating cage translator is designed for the high or low heat flux simulation in the spacecraft thermal vacuum test. With it, the infrared cage can be moved to the top of the heating surface of the spacecraft under high heat flux conditions, or removed under low flux conditions. This paper, based on the analysis of the requirement of the system functions and properties, describes the functional blocks and the design requirements of the translator of the infrared heating cage. The translation device of the infrared heating cage, by a special design, works well without the risks of losing stability or failing in the cryogenic environment, or leading to poor lubrication under vacuum, or overheating of the electric motor. In practical applications, this system is shown to enjoy enough safety and reliability in the simulated space environment.. Some suggestions for improvement in further applications are presented lastly.关键词
