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道設計為斜航線(等傾角螺旋線)槽形,可以大幅度改善燃燒室的冷卻性能.斜航線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,提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母線輪廓復雜,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,研究了斜航線的數學模型,開發了自動編程軟體系統.使用該系統,可以生成多種母線輪廓回轉體外表面上的斜航線數控加工程序.燃燒室收斂-擴張段的母線斜率變化大,加工難度大,是斜航線冷卻通道加工的最典型工件.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,驗證了所開發的斜航線冷卻通道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Transformed the six - bar guide - bar mechanism realizing linear displacement in automatic instruments into a basic rotating guide - bar mechanism, established the mathematical model of velocity approaching constant by the classical approximate synthesis theory and the modern error theory, discussedthe influences of the existent region of main mechanismic parameters on kinematic and dynamic properties, analysed the theoretical transmission ratio error, advances systematic, complete steps and methods for dimensional synthesis of this mechanism with computer aided design

結果表明,在成核的後期階段:最大位移速率單調加速增加;滑動熱點(最大滑動速率處)在後期階段開始自發性遷移,且在空間上連續;當最大滑動速率達到可以明顯探測的量級時(高於載入速率一個數量級以上) ,倒計時間為20小時或更長一些,這時的速率變化可作為臨震預測標志;平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢,由此可推測微震活動增長率與倒計時間同樣存在對數線性關系;正應力的變化對上述時間尺度有延長作用,使之大致增加到原數值的2倍。Capp ( computer aided process planning ) appears with the rapid development of modern machinery manufacture and computer technology. which makes use of the practical experiences of technician to process data, to make scientific decision, to create process regulations automatically, to aid the dimension calculation procedure, to plot working procedure drawings, to choose cutting parameter, to aid optimizing process planning and etc. and it also provides a powerful technological support for the digitalization, intelligentization and autoimmunization of process planning design
