论航天器的热试验

THERMAL TEST OF SPACECRAFT

论述了各种类型热试验(热平衡试验、热真空试验、热循环试验)在航天器研制中的重要性及它们的试验要点。针对当前试验实践中出现的问题,强调了组件级,尤其是电子电工产品热试验(热真空试验及热循环试验)和整星级发射星热真空试验对提高航天器可靠性所起的重要作用,并提出了相应的建议。

The paper discusses the importance of thermal tests of difference types(thermal balance test, thermal vacuum test and thermal cycling test)in the spacecraft development,and also their implementation.Due to the problems occuring in practice work,emphasize has been put on the thermal test(thermal vacuum test and thermal cycling test)on eletronie and electrical equipments and the thermal vacuum test of flight model satellite, Such tests play an important role in enhancing the reliability of spacecraft.some suggestions are put forward.
