中文摘要 本研究主要是應用商用有限元素分析軟體MSC.Software公司產品Patran及Dytran兩套軟體,來進行平面震波衝擊金屬板的作用分析,期望成功的模擬出震波衝擊金屬板的應變狀況。本分析建構與實驗相同大小的銅板做為測試模型,銅板的厚度採用1 ,再運用Patran程式建構模型、Dytran程式進行分析。因為分析對象包含了平面震波與銅板兩項不同的元素,所以進行分析時,必須注意Lagrange和Eulerian兩種不同建模的耦合技巧,才能達到平面震波與銅板交互作用的模擬。運用震波管實驗,配合應變規量測銅板受到入射震波衝擊後的應變值,此時,再與Dytran程式模擬的應變值做比較,以瞭解數值模擬運用的成果及準確範圍。本研究中成功的發展出Dytran程式模擬震波衝擊金屬板的分析方法及有效模擬,除可減少實驗的風險及成本,也可提早預測金屬板受震波衝擊的應變狀況。
英文摘要 In this research, we took advantage of two sophisicated commercial finite element analysis software, the "Patran" and the "Dytran" developed by MSC Software to analysis the plane shock wave impulse on metal boards and to visualize the variation of strain by modeling and simulation. The simulation model is built of identical shell coppers with the thickness of 1 in the analysis software environment with distinctive consideration of different coupling techniques, namely the Lagrangian and the Eulerian to two different elements, to better illustrate the interaction of the simulation. The shock wave tube experiment results are fullfilled by measuring the strain of the shell copper with a strain gauge impacted by the incident shock wave, meanwhile, correlate the results comparatively generated by the "Dytran" to ensusre the accuracy of the numerical simulation. A successful analytical approach is conducted effectively by manipulating the "Dytran" software to simulate the phenomenon of plane shock wave impulse on metal boards, not only the cost and risk of experiments are reduced, but also the strain status is foreknown.
