摘要
Based on the requirement of ultra-cryogenic test for lunar roving vehicle and its component, theoretical analysis was performed in this paper. Gaseous helium cold box was designed and numerical simulation was conducted to optimize the design of cold box. After manufacturing, it was put into use and finished the task successfully. The Test performance of cold box shows that temperature uniformity of the cold box's during the test meets the requirement. The temperature of the cold box can be cooled down to 30K +/- 1K, and the lowest temperature of test specimen is down to -205 degrees C.
