微微衛星的研究可以讓我們瞭解太空任務的需求,並且幫助我們去設計更小、更便宜、更快速、更好的衛星。本論文運用有限元素分析軟體(Patran、Nastran)來分析微微衛星中的結構與熱控次系統。在結構方面,必須考慮載具升空時的影響,依據驗證微微衛星的質心、自然振頻與應力分析的結果,來評估衛星結構設計的可行性。 在熱控次系統方面,必須考慮所受熱源和熱控方法,利用軟體模擬的方式來瞭解衛星在太空中運行時,各插板及各組件的溫度,以確保各次系統可於正常溫度下的運作。 The research of picosatellite can let us to understand the requirements of space mission and help us to design a ‘smaller, cheaper, faster, and better’, satellite. We utilize a finite element analysis software to analyze the structure and thermal-control subsystem in a picosatelite. In structure subsystem, we have to consider the influence during the launching period. According to the results of center of mass, natural frequency vibration, stress analysis, we can estimate the safety in the structure design. In thermal-control subsystem, heat source and the method of thermal control should be considered. Software simulation is used to understand the picosatellite’s temperature variation when it operates in space. All subsystems are assured to be workable work in the appropriate temperature.
