  1. Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly. because the width dimension of loxodrome groove is narrow and the depth is deep, some machining methods are incapable, such as end - milling or electrochemistry. according to the peculiarities, a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched. because most firebox generatrix is composed of complex curves, it is very difficult to get cnc cutting program with manual means. in order to deal with the problem, the loxodrome mathematics model is studied, and an auto - programming software system is developed. the software system can generate cnc cutting program of loxodrome on many kinds of turned surface. the constriction - distension segment of firebox is the most representative workpiece. the sharp changing of its generatrix slope makes loxodrome milling difficult. with the theory analyzing and practice cutting experiment, some applied techniques, which include milling mode and direction, choosing cutter diameter and cutting start point setting, are developed. adopting the technology above, tens regular workpiece have been manufacturing. the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method. the developed technology is also worth to be referenced to other similar workpiece

    將液體火箭發動機燃燒室的冷卻通設計為斜(等傾角螺旋)槽形,可以大幅度改善燃燒室的冷卻性能.斜冷卻槽的槽寬尺寸較小而槽深尺寸較大,所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點,提出了五控制、四聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母輪廓復雜,手工編制數控加工程序難度大.為了解決數控加工程序的編制問題,研究了斜的數學模型,開發了自動編程軟體系統.使用該系統,可以生成多種母輪廓回轉體外表面上的斜數控加工程序.燃燒室收斂-擴張段的母斜率變化大,加工難度大,是斜冷卻通加工的最典型工件.經過理論分析和實際切削實驗,研究了針對該類型工件的片銑刀直徑選擇、銑削方式和方向、刀具調整和起刀點的設置等多項實際的加工方案.採用上述的一系列技術,已經成功地加工了數十個合格工件.經過兩年多的實際生產過程應用,驗證了所開發的斜冷卻通加工方法的正確性和可行性.這些加工技術的研製成功,對其他相似類型零件的加工亦具有參考意義
  2. In this paper, an approach of the systematic artificial neutral net was introduced into the analysis on the ship - against - bridges probability with a computer programs. based on the basic data of the present 12 typical bridges as the sample, 4 chief influential factors as the input coefficient, such as the bridge span, the water flow rate, the incline angle between water flow direction and the direction normal to bridge axis, and the curve in the course near the bridge area, with the ship - against - bridge probability as the output coefficient, the intelligent judging system of the ship - against - bridges probability reflecting the influence of the above input parameters is obtained after training

    本文首次將人工神經網路系統方法引入了船撞橋概率的研究當中,編制了計算程序,成功地以現有12座典型橋梁的基礎數據為樣本,以橋梁跨徑、水流流速、水流方向與橋的夾角以及橋區彎曲度等4個船撞橋主要影響因素為輸入參數,以船撞橋概率為輸出參數,經訓練得到了能較好地反映上述輸入參數影響的船撞橋概率判斷系統。
