为了利用月球观测地球等离子体层的优势,开展了月基望远镜的研究,并对其进行了热设计和热分析。分析了月基望远镜所处的空间环境。对望远镜各个部分进行了热设计;采用被动热控措施控制望远镜的温度水平,降低空间环境的影响;采用热疏导的方式对探测器进行散热。根据月基望远镜的空间环境、结构特点,以及采取的热控措施,在I-DEAS/TMG软件中建立有限元模型,并进行了仿真分析。分析结果:光学系统部分最大温度范围为-50℃～60℃,机械结构部分为-110℃～105℃。热设计方案合理可行,满足热设计要求,其研究方法对其他舱外月基探测器的热设计具有一定的指导和借鉴作用。
In order to take advantage of the lunar observation of the earth’s plasma layer, a Moon-based telescope was developed and its thermal design and thermal analysis were performed. The spatial environment of the moon-based telescope is analyzed. The thermal design of each part of the telescope was carried out. The passive thermal control was used to control the temperature of the telescope to reduce the impact of the space environment. The detector was cooled by heat conduction. According to the spatial environment, structural features and thermal control measures of Moon-based telescope, a finite element model was established in I-DEAS / TMG software and the simulation analysis was carried out. Analysis results: Part of the optical system maximum temperature range of -50 ℃ ~ 60 ℃, the mechanical structure of the part of -110 ℃ ~ 105 ℃. The thermal design scheme is reasonable and feasible to meet the thermal design requirements, and its research method has certain guidance and reference for the thermal design of other extracluster lunar probe.
