中文拼音 [húsānjiǎoxíng]
弧三角形
英文
spherical triangle-
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。In this paper, ansys, the software on finite element analysis, is made use of processing the static and modal analysis on the preliminary models and its " modified ones. by analyzing the results, we can conclude that the stresses on the components of the modified models are tended to equilibration and the location of the branches " brace can also influence stresses and translations on the branches. in addition, the values of the intrinsic frequencies on modified models " are larger than the ones on preliminary models, but the ranges of the frequencies on both models are almost same
傳統的弧形閘門的支臂結構基本上都是三角架式的，這主要是因為按平面體系進行計算的傳統設計方法忽略了結構的整體性及弧形閘門的空間結構特點，設計得比較保守，而實際上，將其改為a型結構也存在可行性，本文是利用有限元分析軟體? ? ansys對原模型及修改模型分別進行靜態和固有頻率的計算，通過分析比較其結果可知，支臂改為a型后會使閘門的整體受力趨于均勻，即原模型受力大的部件其應力變小，而原模型受力小的部件其應力會變大；而且a型支臂的支桿在不同的放置位置對支臂的應力和位移變化也有一定的影響。It can make triangle, rectangle, positive five squareness, positive hexagon, roundness and so on
