The numeric calculation in fea method 橋梁結構有限元分析中的數值計算
Hyper - voltage numeric calculation 過電壓及數值計算
Method to determine the type used to contain the result of a numeric calculation 方法確定用來包含數值計算的結果的類型。這取決于結果數字的存儲要求。
Through tests the paper studies the relationship between shear strength and water content of hefei expansive soil . a one - dimension numeric calculation model about the moisture variety in unsaturated expansive soil is built 實驗研究了合肥膨脹土抗剪強度指標c和與天然含水量之間的關系,并提出合肥膨脹土隨含水量變化的抗剪強度公式。
This is a novelty of the paper . in heat transfer there are problems in converting a mass of data , which is from numeric calculation and hardware collection , to visual image ; these problems have many relations with the applications of heat transfer relevant subject 這是本課題研究的一個新穎之處,在熱力傳導中,大量存在著將數值計算及硬件采樣所獲得的大量數據轉化為可視化圖像的問題;這一問題與傳熱學相關學科的可應用于實際中有著密切的聯系。
As a result the prototype that was function satisfactory and user friendly , has developed with vb and matlab commercial software . because the numeric calculations are all done by anns , the software is able to transplanted and embedded in different blast furnaces and different software 利用數據庫中30組數據對系統進行輸入以訓練神經網絡,當顯示訓練完畢后,將數據庫中剩余的27組數據輸入以對神經網絡對高爐鐵水硅含量預測結果的命中率進行檢測。
On the basis of theoretic analysis and numeric calculation , the author verifies that only is the ratio of the fundamental period of the structure to the disturbance period beyond 1 . 4 , it ' s possible to achieve reductions in both the relative displacement and the absolute acceleration responses 作者在此基礎上,從理論分析和數值計算兩方面證明了粘性變阻尼控制僅在結構周期與激勵主周期的比值大于1 4時才有可能同時減小結構的位移反應峰值和加速度反應峰值。
We give a mathematical proof for the model - approximately independence of anc coefficient . combining a concrete nuclear reaction , we check up the model - approximately independence of anc coefficient with numeric calculation . under the el transition condition , a expressions with anc coefficient to compute the cross section of radiative capture reaction has been given in this thesis 我們對anc系數的近似模型無關性給出了一個數學形式理論證明,并結合具體的核反應,利用數值計算驗證了anc系數的近似模型無關性;在e1躍遷情況下,我們給出了一個用anc系數計算輻射俘獲反應截面的計算公式。
Because the model used in the paper is different from other methods of judgment to slagging , all the variables affecting slagging are assigned the local values resulted from numeric calculation ( in other methods , the parameter to affect slagging can only use one flag value ) . hence , the judgment to the slagging condition on any specific node of the grid can be made , so that effective and timely measures can be taken during operation 因為,與其它結渣評判方法不同的是,本文的模型中,影響結渣的各變量全部用數值計算結果得到的當地值(其它判斷方法所用的參數,對一臺爐子只用一個標志值) ,這樣給出的是受熱面上任一網格節點的結渣情況,以便運行過程中及時有效地采取措施。
On one hand , the internal forces and displacement formulas of csbcs were deduced by using the matlab program , on the other hand , taking out of one wavelength of csbcs and soil from the actual project as the analysis object , simulation numeric calculation was carried out by using big - style fem ( finite element member ) software , ansys 一方面,用matlab編程,推導了波紋鋼板橋涵的內力和位移公式,另一方面,取一個波紋長度的波紋鋼板橋涵和土作為分析對象,用大型有限元軟件ansys對湖北洪沙線豐收渠橋涵工程的靜載試驗進行了模擬數值計算。
