Abstract : this paper studies the structure, function and realization of ceramic / metal gradient thermal barrier coatings dynamic design software by combining the conceptions of thermal barrier coatings ( tbcs ) and functional gradient materials ( fgms ). through a typical example, it compares and analyses the simulation results of temperature field in the multiplayer gradient cylinder model calculated by analytical method, finite difference method and finite element method
文摘:結合熱障塗層和功能梯度材料的概念,研究陶瓷/金屬梯度熱障塗層動態設計軟體的結構與功能及其實現過程.通過具體的例子,對多層圓筒模型的溫度場的解析解、差分解及有限元解的模擬結果進行了比較及分析 -
Based on the results of previous researchers, the following instigations have been carried out in this paper : ( 1 ) employing a reasonable local resonance model which can accurately embody the heat - generation behavior due to resonance and vibration - heat mode in delaminated region, the dynamic response and temperature distribution in the small delamination region of a laminated beam are formulated. influence of the excitation frequency on the temperature gradient formation is analyzed numerically, and several meaningful conclusions are drawn. ( 2 ) for laminated plates with delaminations, due to complexity of the analytical solution, the finite element method is employed to analyze their temperature distributions and satisfactory results are also obtained
本文在前人研究的基礎上,對此方法進行了進一步的探討,主要做了以下的工作: ( 1 )選取合理的、能夠準確反映由共振而產生熱量的行為的局部響應模型,以及合理的振動熱模式,推導了一維層合梁小脫層區域的振動響應及梁的溫度分佈,並編製程序計算了該層合梁在激勵一段時間后的溫度分佈趨勢,分析了激勵頻率對溫度梯度形成的影響,得到了一些有意義的結論; ( 2 )對於二維層合板,由於解析解的形式異常復雜,本文採用有限元計算軟體對其溫度分佈進行了分析,也得到了較為滿意的結果。
