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Promax tension ind corp has long sold and manufactured a variety of custo mized air shafts / air chucks / safety chucks, edge position control systems / epc, powder / air / disk brakes and clutches, ac / dc motor control systems, re - winding / un - winding systems, tension control systems, web inspection systems, automatic color register systems, servo - vector control systems, mmi interface and supervisory control and data acquisition ( scada ) systems and others such as slitting, winding, laminating, extruding, coating, and gravure printing machines, even other auxiliary devices etc. for webs such as paper, films, rubber, textiles and foils

復雜的旋轉機械往往由軸承、齒輪等大量零件構成，在對這樣的設備進行狀態監控和故障診斷時，為提高故障隔離率，通常需要為每個零件就近安裝傳感器，但由於機械結構的緊湊性和性價比的限制，這一點往往難以實現。Three axis optical tracking test table is a kind of powerful instrument used to reproduce the flying posture of flying weapons in laboratory. the test table, together with equipment producing target, simulates the attacked target and flying missile, which can really simulate the various flying postures in space and dynamic characteristics. thus, the performance of sensors, control system and actuator and so on can be tested and evaluated, which provides various reference bases for developing, improving and redesigning flying weapons
三軸光學跟蹤試驗轉臺是一種在實驗室條件下復現飛行器或導彈在空中飛行姿態半實物模擬的有力工具，它和目標發生裝置組合在一起模擬導彈跟蹤目標的過程，可以真實地模擬出導彈等飛行器在空間的各種姿態和動力學特性，從而對其傳感器件、控制系統和執行機構等硬體設備的性能加以測試和評價，為飛行器的研製、改進和再設計提供各種參考依據。Abstract : the bearingless induction motor, which combines the induction motor and magnetic bearing is a strongly coupled complicated nonlinear system ; the decoupling control of the electromagnet torque and radial levitation force is the base of the stable operation of the bearingless motor
文摘:無軸承異步電機是一個強耦合的非線性復雜系統，實現其電磁轉矩和徑向懸浮力之間的解耦控制是該電機穩定運行的前提。The table is a important device in the hardware - in - the - loop simulation system, and it simulates the flight of unmanned aerial vehicle so as to achieve flying parameters from those sensors. the signals of sensors in the table are transmitted by many cables previously, thus it confines the movement range of the three - axis frameworks. as the perfomance of uav become complicated, the signals cables are replaced by wire rings in some tables, but it brings many difficulties and unreliable factors for the simulation table ’ s design also. bluetooth, as a new short - range wireless communication technology, is a reasonable and feasible scheme in this condition
三軸模擬轉臺是無人機地面半實物模擬系統中的重要設備，用來模擬飛機在空中的姿態和角運動，以驅動傳感器產生飛行姿態、角速度及角加速度信號。早期轉臺上傳感器信號通過穿在框架中的電纜進行傳輸，這就限制了框架的運動范圍。隨著無人機任務的復雜程度不斷提高，出現了採用導電滑環傳遞信號的模擬轉臺，但這也給轉臺設計帶來了困難，且存在不可靠因素。分享友人
