摘要：
To solve the problem of uneven temperature distribution in the ground simulation experiment of space environment by space optical remote sensor, the modular design is used to optimize the cabin plate structure frock of a certain space optical remote sensor, and the cabin plates are divided according to the temperature distribution. In this paper, modular assembly and modular thermal control are proposed. The modular assembly is to divide the cabin plates and its surface heating sheets independently; the modular thermal control considers the cabin plates as a whole, and only the heating sheets are divided. The results show that the average temperature deviation of the modular thermal control is 0.205 K, which is lower than 0.87 K of the unmodulated design and 0.30 K of the modular assembly, and improves the temperature uniformity of the cabin plates. Modular assembly improves the temperature distribution of the cabin plates, and the proportion of measuring points that meet the thermal control requirements is increased from 34.8% to 96.7%. However, there is still a certain temperature difference between the modules, and modular thermal control eliminates the temperature difference. The proportion of measuring points meeting the thermal control requirements is further increased to 100%, which fully meets the thermal control requirements. © 2019, Editorial Board of JBUAA.
