由國立中央大學師生開發的深太空輻射探測儀（Deep Space Radiation Probe, 簡稱DSRP）準備加入日本民間ispace的Hakuto-R Mission 2（M2）登月任務，將過去累積的IDEASSat任務開發經驗結合加以改良的游離輻射容忍度，深入了解太空輻射環境對立方衛星的影響。本論文聚焦於使用有限元素分析（FEA）軟體ANSYS Workbench和電腦輔助設計（CAD）軟體SolidWorks對該酬載工程體進行數值模擬分析，包含線性靜態的等效應力、等效應變和總變形分析，以及線性動態的自然頻率、模態與隨機振動分析。為了對比兩種不同類型軟體的模擬功能，本研究將動態模擬結果與先前研究中之振動實驗的結果進行比對和驗證，模擬結果與實驗結果大致吻合。但發現SolidWorks較適合初學者創建零組件，其內建的有限元素求解器在材料和網格的選擇上較少，導致分析時間較短，結果也較不精確；而ANSYS Workbench則具備混合式網格劃分和精確的準靜態模擬選項，其數值模擬結果與先前研究中的實驗結果一致性頗高，顯示其準確性。此分析技術與經驗可以提供小型酬載更準確的數值數據和更方便的模擬程序，此外，本研究也針對未來深太空輻射探測儀飛行體提出對應的結構改善方案。;The Deep Space Radiation Probe (DSRP) developed by the students and faculty of National Central University is scheduled to land on the Moon with ispace Hakuto-R Mission 2 (M2). It is hoped to characterize the deep space radiation environment to quantify its effect on spacecraft electronics and biological organisms. This thesis project concentrates on comparing numerical analysis solutions of the DSRP engineering model, using finite element analysis (FEA) software ANSYS Workbench and computer-aided design (CAD) software SolidWorks. The studied events are focused on the linear quasi-static analysis of equivalent stress, equivalent strain, and total deformation, as well as, linear dynamic analysis of natural frequencies, mode shapes, and random vibration. The idea is to understand better the functions and results produced by the two types of software and to utilize the results to determine the possible improvement for future DSRP structural design. The numerical results of natural frequencies and mode shapes, and random vibration analysis are verified using experimental vibration testing results from the previous studies. A comparison between the two analysis tools shows that SolidWorks is intended to allow relatively inexperienced users to quickly and easily create 3D parts. Its built-in FEA solver has a relatively simpler material library and meshing techniques. However, ANSYS Workbench has hybrid meshing and quasi-static options which can provide more accurate and consistent FEA solutions. Using models built from SolidWorks in linear static and dynamic analysis in ANSYS Workbench for future small payloads will save the design team the stress of manufacturing multiple models before the system gets qualified.
