  1. The welding technology of francis turbine runners is optimized from the view of subsection welding and local heating by numerical simulation. the result shows that welding residual tensile stress appears in the weld and its area nearby, and peak stress appears in the dangerous area of blades after practising quondam welding technology ; welding residual tensile peak stress in the dangerous area of blades can be decreased by welding both ends earlier and then welding middle section later during subsection welding, and decreasing effect on welding residual stress of the subsection welding is related to the weld length of blade outlets and welding direction of each subsection ; decreasing effect on residual stress of the local heating is direct proportional to heating time, heating temperature, heating area, and inversely proportional to cooling area, and welding residual tensile peak stress in the dangerous area is decreasing trend earlier, and then increasing trend later with heated location increased

    本文利用數值模擬手段對轉輪的焊接工藝從分段焊和局部加熱兩個方面進行了優化，結果表明:採用普通工藝焊接時，葉片焊后殘余拉應力出現在焊縫及其附近區域，並且在葉片出水邊的熔合線附近（危險區域）出現了峰值;在採用優化的分段焊時，先焊兩端后焊中間的方法可以降低葉片危險區域的焊接殘余拉應力峰值，降低效果與葉片出水邊焊段長度、焊縫各段的焊接方向有關;局部加熱法降低轉輪危險區域殘余應力的效果主要與加熱時間、加熱溫度以及加熱面積成正比，與冷卻面積成反比，並且危險區域的殘余應力隨加熱區域的增大呈先降低后升高的趨勢。
  2.

    計算結果表明：塔壁外側在冷卻水面到達的瞬間進入塑性屈服，筒節中部塑性屈服區較大，當靠近焊縫時塔壁的塑性變形區逐漸縮小直至消失，塔壁塑性屈服區的分佈特點解釋了塔體長期使用后發生鼓凸變形及簡體與焊縫連接處產生裂紋的原因。
  3. 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：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；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的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；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的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：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的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。
  4. The meltable liquid touches with the rotary drum of cooling that form material film in rotary drum appearance. the heat exchange between material film and drum wall makes material film cooling and crystallization. the crystal material film is cut by scraper which forms piece product

    轉鼓結片是一個冷卻結晶過程，料盤中熔融料液與冷卻的轉鼓接觸，在轉鼓表面形成料膜，通過料膜與鼓壁間的換熱，使料膜冷卻結晶，結晶的料膜被刮刀刮下，成為片狀產品。
  5. The advantage of this air conditioning, that is energy conservation, is for energy to overheat or overcool air in traditional air conditioning is saved with radiation directly acting to human ' s body. so, the radiant heat exchange between human body and enclosure was made as main point of this paper that the radiant heat exchange model was established and the radiant heat exchanges of different human body in different sites were calculated in detail

    本空調方式的先進性，即節能性，是由於採用了輻射方式直接對人體進行供冷、供熱，從而省去了傳統的過度冷卻或加熱空氣所消耗的那部分能量而表現出來的；因此，本文把人與室內環境之間的輻射換熱作為一個重點，建立了輻射板等室內壁面與人體間的輻射換熱模型，並詳細計算在不同位置各人體部分與室內環境之間的輻射換熱。
  6. Ultrasonic plastic welding theory is generated by the generator 20khz or 15khz pressure, high - frequency signals, the system can be adopted for the high - frequency signals into mechanical vibrations, and in plastic products working, through working surface and internal friction among elements spread by the department of the interface temperature, when the temperature reached the melting point of her own, that the working interface rapid melting, and then fill in the gaps between the interfaces when shock stop working at a certain pressure and cooling will be a perfect welding

    的高壓高頻信號通過換能系統，把信號轉換為高頻機械振動，加於塑料製品工件上，通過工件表面及內在分子間的磨擦而使傳處到介面的溫度升高，當溫度達到此工件本身的熔點時，使工作介面迅速溶化，繼而填充于介面間的空隙，當震動停止，工件同時在一定的壓力下冷卻定形成完美的焊接.點擊數： 723錄入時間： 2006 - 5 - 14
