月面巡视探测器太阳帆板热电耦合仿真计算

文章建立了月面巡视探测器太阳帆板热电耦合计算模型,制定了太阳帆板的对日定向方案和输出电能分配方案.通过数值模拟获得了月面白昼期间太阳帆板的温度及电能输出,分析了太阳帆板背面包覆隔热材料前后及帆板是否对日定向的计算结果.计算表明:当帆板不对日定向时,其背面包覆隔热材料对其温度及电能输出无明显影响;对日定向时,帆板温度随时间的分布规律发生了明显改变,此时帆板背面包覆隔热材料使其温度明显上升,但帆板正面与背面的温差减小.

Calculation of thermoelectric cogeneration on the solar panels of a lunar rover

A cogeneration model is established to calculate thermoelectricity coupling on the solar panels of a lunar rover.Programs are developed for sun tracking and power distributions.The temperature and power output of the two solar panels are calculated and analyzed during lunar daytime.Results are given accordingly for cases with or without insulating material covered on the backside of each solar panel,as well as with or without sun tracking.The results indicate that the effects of the back-covered insulating material on the temperature and power output of each panel is not significant when the solar panel is not oriented to the sun,but the temperature distributions changes significantly with time when the solar panel is directed to the sun with the average temperature being increased while the temperature difference between the front and back side of solar panel being decreased.
