摘　　要：文章首先对月面巡视器的基本构型及围栏的用途进行简要介绍,并通过热分析计算指出当前围栏设计的利弊。针对围栏所带来的月昼期间工作温度偏高的问题,提出了4种围栏构型方案,对这些方案进行了热分析研究和对比分析,从中选择出工程可行的最优方案,使得设备在月昼和月夜下的温度均满足设计指标要求。This paper first reviews the basic configuration of a lunar rover and the role played by its radiating surface fence.The advantages and disadvantages of the fence are then discussed through thermal control analysis.With due consideration of high working temperature caused by the fence during lunar day,four kinds of design schemes were worked out for the fence configuration.The thermal control analysis and comparative analysis were carried out for these schemes,and the acceptable engineering scheme was selected from them.The scheme could meet the requirement for the temperatures of the equipment in lunar day and night.
