  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,造成輸出流量脈動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流,在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲,本文以截流作用和液體的可壓縮性為理論依據,以matlab語言為工具,對原配流盤上的v型尖槽進行了理論計算,繪制出p - t圖線,分析了它的不足,並對原有v型尖槽進行了優化設計,得出了v型尖槽的最佳幾何尺寸:配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ,槽長5mm ,槽的橫截面為等邊三角形。
  2. In this way, when obturation cubage leave absorb oil cavity it connects the eduction oil cavity with the v trough and with the increasing of the turning angle, the size of the cross section of v trough become bigger and bigger, which make the pressure between the cavity of two blades much higher and higher, and until it completely connects the eduction oil cavity, it reaches the pressure of the eduction, and it can effectively reduces the fluid noise caused by high pressure return flow

    這樣,當密閉容積離開吸油窗口之後,通過v型尖槽逐漸與排油窗口連通,隨著轉角的增加, v型尖槽通流截面積逐漸增大,這就使兩葉片間容腔內的壓力逐漸升高,直至完全接通排油窗口時,才升壓達到壓油腔的壓力,這樣可以有效地降低因高壓迴流而引起的流體噪聲。
  3. Abstract : based on the mathematical models of roll speed for cross - rolling elongation process, the effects of toe angle on roll speed, local feed angle and local angular velocity, and also on material flow are analyzed. by the analysis, the toe angle can be optimized

    文摘:基於建立的斜軋延伸機軋輥速度模型,模擬分析了沿軋制方向和螺旋方向上輾軋角對軋輥速度、局部送進角、局部角速度的影響,進而分析了這些參數對金屬變形和流動的影響,據此可優化輾軋角。
