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 流體噪聲主要來源于輸出流量脈動,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回流,在配流盤上開設v型尖槽可降低因高壓回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,并對原有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。 |

The current trends of this field is to acquire the current density of dipole distribution rather than a few dipoles . based upon that , a new model was proposed - dipole layer localization method ( dllm ) : spherical dipole layer was used as source model , on which dipoles were distributed by equilateral triangles ; three concentric inhomogeneous sphere was used as head model , which contains scalp , skull and cortex with different conductance . the dipole distribution and scalp potential tomography were obtained with singular value decomposition ( svd ) 鑒于該領域的研究趨勢已從求取少數偶極子過渡到偶極子分布密度的獲得,本文提出了新的模型? ?偶極面定位方法( dipolelayerlocalizationmethod , dllm ) :以等邊三角形均勻分布的偶極子構成的偶極面(球面)作為源模型;包括頭皮、顱骨和皮層的三層同心介質球作為頭顱模型,運用奇異值分解來求解逆問題,從而獲得偶極子分布和頭皮電位分布,實現三維成像。 |
