  • 本論文主要配合大亞灣反應堆微中子實驗研究計畫,分析主探測器之核心組件-中、內層之壓克力圓柱殼桶,其不同之模型在組裝及運送過程中的受力情形,並分為靜力分析與動力分析進行探討。
    使用有限元素套裝軟體ABAQUS之前處理CAE建立不同之模型,採用靜力分析模擬在製作時承受自重之結果,並與實驗試體所得之結果做比較,驗證本論文建立之分析模式為正確且合理,並評估此設計是否為優良。採用動力分析模擬不同之設計模型在裝滿水後,於隧道內之運送過程,因為路面顛簸,使得模型瞬間受到加速度作用之結果,並評估此設計是否優良。
    最後,將靜力分析與動力分析之結果做出歸納與討論,以期能運用於大亞灣反應堆微中子實驗研究計畫,使得該計畫進行更為順利。

    The study a part of Daya Bay Reactor Neutrino Experiment, mainly analyze the major parts in the detector - the inner and middle layers of the acrylic vessel. The static analysis and the dynamic analysis are used to explore the stress of different models created during the process of assembly and shipment.
    Use ABAQUS to establish different model which analyze dead load in static, and compare with the result of the experiment. Then, confirm the correctness and appropriateness of the analytic pattern of the present study and assess whether the designs are good. With dynamic analysis, the designs with water are probed to see the stress generated by the acceleration during the process of shipment in the tunnel. Again, assess whether the designs are good.
    Finally, the results of the static analysis and the dynamic analysis are induced and discussed with the hope that they can be applied to the Daya Bay reactor micro neutron experimental study plan and make the plan better.
