摘要為條理出製程參數之函數關系,作為開發雙金屬固態輥壓接合新製程之參考,本文在既有之滑線場理論基礎上試從磨潤熱力學之角度探討雙金屬輥壓製程中母材介面之質互動問題。Fem analysis of associated and non - associated flow rules in theory of slip line field
滑移線場理論中不同流動法則的極限分析有限元解The movement law that abrasive fluid in centrifugal field is discussed through the analysis of experimental results of high - speed photography, and it is pointed out that in the course of abrasive moving both the moving of layer and the curve changing from front interface to slip are the important factors of influencing processing results
文中通過對高速攝影實驗結果的分析,探討了磨料流在離心場中的運動規律,指明磨料流在運動過程中,其滑移層的運動及前沿界面曲線的變化是影響加工效果的重要因素。According to the aircraft taxi law and the conflicts on taxi routes, a mixed integer linear programming formulation was modelled based on the standard taxi routes
根據飛機在機場地面的運動規律,基於確定的滑行路徑,考慮滑行路線沖突,建立了該問題的混合整數規劃模型。( 4 ) on the basis of analysed result and the status quo of huxi bank, computing the slope safety and seepage of bank by fem. the result shows that the tarus quo of huxi bank could not satisfy theslope safety on designed flood lever. after the reinforcement of seepage, the method can not only reduced leakage, debace the soggy but also ameliorate stress fields. lt also can reduce horizontal displacement and certical displacemeng which have disadvantages to bank
進行堤體防滲加固后,不但可以減少滲漏,降低堤身浸潤線,還可以有限度地提高抗滑穩定安全系數,改善堤身及地基的應力場,使在高水位作用下產生的不利於堤體安全的水平位移和豎向位移減小。對在後繼采動中可能造成的防滲材料的破壞進行了校核,結果表明材料是安全的。It is validated that the numerical methods can absolutely predict the flow in the microchannels. the flow field around the roughness and the pressure drop of midline along flow direction are analyzed. it ' s found that the range of the pressure drop change relate to the magnitude of relative roughness, the distance between two parallel planes, the re number and ratio of the size of roughness and the distance between two roughness
通過對粗糙元周圍流場和充分發展段中心線壓力曲線的分析,發現有粗糙元存在的兩平行平板間微通道,其充分發展段壓降大於光滑平板充分發展段壓降;當相對粗糙度和re不變時,隨著板間距的減小,粗糙度對主流的影響不斷增大;當板間距和相對粗糙度不變時,在層流狀態下,粗糙度對流動的影響不隨re的變化而變化;當板間距和re保持不變時,相對粗糙度越大,其對流動的影響就越大。分享友人
