飛機起落架作為飛機結構的一個重要部件,承受著飛機與地面接觸時產生的靜、動載荷,吸收和消耗飛機在著陸撞擊、跑道滑行等地面運動時所產生的能量,在減緩飛機發生振動,降低飛機地面載荷,提高乘員舒適性,保障飛機飛行安全等方面發揮著極其重要的作用。Energy conservation and and reformation of power plants " heat installation affect a lot on the efficient performance of opertion of power plant. pump and fan take a large proportion in power plant and resume much electric energy. so there is much energy conservation pationlity in them. and we should have strong tools and theories " support to reform them. we can combine the theory modeling and engineering design manufacture by the bussiness software such as fluent. in order to take full advantage of the powerful function of fluent and increase absolutely its conveniece and interaction, we should develop fluent secondly. this paper puts the idea firstly demostricly to substitute the performance test of pump and fan to get the integrative system of the optimization and computer aid design, and so we can increase greatly of the efficiecy and quality of the facility reformation. the main idea about the secondary development of fluent in this paper is based on the secondary development of gambit, the modeling and meshing s oftware of fluent, and simplify the modeling and meshing of gambit. meanwile, the data management base on web browser kind is adopted for the convenience of optimization and parameterization, and the journal files createdly recently can get new medeling and meshing files that can be used by fluent. so the designer can focus on the computer scheme and the result analysis without care the fussy designing and optimiziation. so we can increase greatly the optimization efficiency
泵與風機在電廠中占較大數量比例,且消耗大量電能,節能潛力巨大,對其改造需要強有力的工具和理論支持,用商用cfd軟體如fluent可實現泵與風機改造中的理論模擬與工程設計製造間的結合。為了充分發揮fluent的強大功能,又能最大程度地提高其方便性與交戶性,應對其進行二次開發。本課題在國內首先提出對fluent進行二次開發,替代泵與風機性能試驗,形成一體化的優化、輔助製造系統,可大大提高設備改造的效率與質量,其主要思想是基於fluent的cad構體軟體gambit進行二次開發,簡化了泵的構體過程,同時,為了優化及參數化方便,採用基於webbrowser的數據管理方式,生成新的記錄文件同時產生新的fluent計算能識別的圖形網格文件,這樣就將設計優化者從繁瑣的圖形設計及優化中解脫出來,專注于對計算方案的確定及計算結果的分析,極大地提高了設計優化的效率。Through adjusting the controlling fuel injection - - regulations of the two injection timings and proportions, an adequate air and fuel charge stratification was produced - we call it quasi - homogenous mixture and the lean burn was successfully realized in a product 4 - valve s. i. engine whose structures are n ' t changed at all. investigations show that twice electronic fuel injection can make the lean limit ( a / f ) increase by 1. 5 - 2 units ; the fuel consumption and exhaust emissions are improved remarkably, in partial load, compared with the product 4 - valve s. i
研究結果表明:兩次噴油可拓展發動機稀燃極限1 . 5 - 2個空燃比單位,最高達23 . 5 ;發動機燃油消耗同原電噴發動機相比可降低19 . 1 % ;整個空燃比范圍內,經過優化的兩次噴油稀燃的最低油耗較單次噴油稀燃下降6 . 5 %左右,各種排放物機內生成量均有大幅度下降。The explicit method is widely used for its simpleness and little memory consumed with local time step and variable coefficients implicit residual smooth to accelerate the convergence procedure. according to yoon and jameson ' s ideas, an efficient implicit lu - sgs algorithm is carefully constructed by combing the advantages of lu factorization and symmetric - gauss - seidel technique in such a way to make use the l and u operators scalar diagonal matrices, thus the numeric algorithm requires only scalar inversion. the computational efficiency is greatly improved with this scheme
顯式方法具有簡單,消耗內存小等優點,並採用當地時間步長、變系數隱式殘值光順等加速收斂措施,在定常流動的模擬中得到了廣泛的應用;根據yoon和jameson提出的簡化正、負矩陣分裂,構造的l 、 u運算元只需進行標量對角陣求逆,極大提高了流場數值求解過程的計算效率;採用newton類型的偽時間子迭代技術使時間推進精度提高至二階。To design multistage depressed collectors. to classify electrons by their speeds, electrons with high energy are collected by low potential and those with low energy collected by high potential ; to try to avoid second electrons " emission. besides those air pump system was introduced briefly. 4
將電子按速度分類,高電位收集動能小的電子,低電位收集動能大的電子,使收集極幾乎不消耗能量,同時盡量避免二次電子的發射,保證行波管的工作穩定性,此外還簡單介紹了下氣體電動態系統。The result of experiment shows that this method does use a little more excess time, meets real - time performance too and obtains satisfactory visual quality for the reconstructive image
