    Abstract: 本論文主要是運用有限元素分析軟體來模擬微微衛星在太空軌道上的溫度分布,並以此評估衛星熱控子系統的可行性。 在熱控,分析時需考慮受熱源、熱控方式和材料性質等,再利用有限元素分析軟體(Patran&Nastran)去計算衛星各子系統、零件和各插板等衛星組件的溫度,以確保衛星能在安全的溫度下操作。 文中探討最熱、最冷、不穩定和內熱源等不同的情況之溫度變化,最後再探討若未加熱控裝置時溫度的變化,以證明衛星熱控的重要性。 The research utilizes a finite element analysis software to simulate the temperature variation condition of a picosatellite on the earth orbit and estimate the workability of the thermal-control subsystem of the picosatellite. In the thermal-control subsystem, heat source, methods of thermal-control and properties of material must be considered simultaneously. A finite element analysis software is utilized to estimate and analyze, the variation of temperature in any subsystem component and board. All subsystems must be assured to perform safely within its appropriate temperature range. Different situations, such as: the hottest the coolest conditions, unstable heat source and inner heat source are taken into consideration. Finally, the variations of satellite temperature without thermal-control is calculated and compared to exhibit the importance of the thermal-control.
