| 目的解决在航天器真空热试验中，单纯依靠红外加热笼自身设计，无法兼顾高、低温工况外的热流模拟需求问题。方法设计一套运动驱动系统，并应用于型号试验，通过调整红外加热笼的相对位置，调节不同工况下外热流模拟能力。结果该系统满足空间环境模拟器机械和电接口要求，克服了真空热试验环境高真空、超低温等因素的影响，实现了红外加热笼的平稳可靠移动，使其最大、最小辐射热流密度等指标得到显著提升。结论真空热试验中，通过运动驱动系统适时调整红外加热笼的相对位置，可以使其更好地适应不同工况需求，并提高外热流模拟整体能力。 |

| ObjectiveTo solve the problem that it is unable to satisfy both the high and low temperature condition needs for heat flux simulation solely depending on design of infrared heating cage in vacuum thermal tests.MethodsA movement driving system was designed and successfully used in project tests. The capability of heat flux simulation was vacuum thermal tests；infrared heating cage；heat flux simulation；movement driving system regulated by adjusting the relative position of infrared heating cage under different conditions during the tests.Results The application results indicated that this system could overcome the impact of high vacuum and ultralow temperature environment，satisfy the mechanical and electrical interface requirements for space environment simulator and drive the infrared heating cage to move steadily and reliably，and acquired an obvious improved index for heat flux simulation.ConclusionIn vacuum thermal tests，by adjusting the relative position using movement driving system can make the infrared heating cage to satisfy the needs much better for different conditions and improve the synthesis ability for heat flux simulation. |
