  1. Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle

    流體噪聲主要來源於輸出流量脈動,造成輸出流量脈動主要因是閉死容積在大圓弧段壓力切換時產生瞬時高壓迴流,在配流盤上開設v型尖槽可降低因高壓迴流而引起流體噪聲,本文以截流作用和液體可壓縮性為理論依據,以matlab語言為工具,對配流盤上v型尖槽進行了理論計算,繪制出p - t圖線,分析了它,並對有v型尖槽進行了優化設計,得出了v型尖槽最佳幾何:配流盤平面上v型尖槽兩邊夾角為12 . 3 ,槽長5mm ,槽橫截面為等邊三角形。
  2. The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

    試驗結果表明:所選、形狀及純度可滿固體潤滑劑性能要求;聚四氟乙烯樹脂熱分解溫度超過400 ,但在ptfe中加入無機填料會使復合材料吸水率提高,熔融溫度及分解溫度降低,且伴有氧化分解反應;碳纖維表面含有c = o及c - o - c等極性基團,有利於提高其與其它組分相容性,提高層間剪切強度;均勻設計試驗方法能夠用較少試驗次數找出配方與摩擦性能間關系,擬合曲線基本能表示各配方摩擦系數發展趨勢;配方中不加銅粉或不加石墨,其摩擦系數均較高,說明銅粉和石墨應該配合使用;當銅粉15份、石墨60份時,銅粉30份、石墨30 - 40份時,銅粉60 、石墨15 - 30份時,摩擦系數均具有較低值;純聚四氟乙烯樹脂在空氣冷卻時結晶度最大,磨損量也是三者中最大;同時,固體潤滑劑試樣在空氣冷卻時磨損量也是三者中最大:不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副,在金屬表面均可形成潤滑轉移膜,從而減少金屬摩擦副表面間直接接觸,大大延長其使用壽命;轉移膜中主要含有較多石墨、少量聚四氟乙烯、 moo 。
  3. Eight trapezoid labyrinth flow - channels are designed through modification to the cell dimension and the number of flow cells based on the parameterized structural design. integral emitter prototypes combining exterior hull and exterior flow - channel are built using rapid prototyping technique, and structural dimension of those flow - channel are measured by optical microscope, the measuring results showed that the design can completely meet the requirement of emitter accuracy

    文中以參數化設計思想,通過改變梯形迷宮流道單元和單元數設計了8種梯形迷宮流道,採用快速成形技術製作出外管與內迷宮流道一體化滴頭型;利用最小標注為50nm光學顯微系統對滴頭流道結構進行了測量,分析結果顯示流道精度完全滿滴頭製作要求。
  4. Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge

    橋梁局部損壞較嚴重,主要因是主梁截面過小、肋板過于薄弱,造成單梁抗扭剛度不;保護層厚度不夠導致鋼筋外露引起銹蝕,降低了橋梁耐久性;各主梁採用橫隔梁連接成整體,橫隔梁剛度越大,橋梁整體性越好,但調查結果顯示,實際情況中並不能達到理想整體剛度。
  5. In allusion to section modality and transverse joint of common span bridges, we choose two kinds of calculating theories in transverse distributing calculate process : the theory of rigidity crossbeam and the theory of hinged girder and slab. making the use of the theory of optimized design, i constitute mathematics model and choose appropriate calculated method. and find the form and detail dimension of section when beams of the bridge satisfy bending moment ^ shearing force and torsional moment

    在用橫向分佈理論計算單梁扭矩過程中,針對現有常用跨徑橋梁截面形式和橫向連接狀況,選取了兩種計算理論:剛性橫梁法和鉸接梁(板)法,利用結構優化設計理,建立主梁承載力數學模型,選擇合適優化計算方法,得出在滿彎剪扭承載力要求時主梁細部
  6. Firstly, the domestic researches, which have been reported, are introduced. then the characteristic of the system in estimation of prestressing losses is analyzed by theoretical method, and the reasons that the elimination of tendon is large and test results are not consistent are pointed. using fem software ansys, anchorage zone of pylon are analyzed

    論文首先介紹了國內現階段對該問題一些研究成果,然後從理論上分析了小半徑大噸位環向預應力體系在計算預應力損失方面特點和造成張拉伸長量偏大且實測數據離散性較大因,並採用國際權威有限元分析軟體? ? ansys從理論上進行分析和索塔錨固區最不利節段模型試驗進行校驗。
