流體技術(shù)舞蹈手臂肌肉：低速的手臂最初有反應，但在時間過長便急劇抽搐，如預期的一樣不均勻地運動。導線似乎比沒有手臂肌肉震動更劇烈。第一層的繞組已經(jīng)從最初的地方向內(nèi)約300毫米。在高速時手臂沒有回應，只是均勻的立場振動。流體肌肉蓄電池技術(shù)：動力蓄電池的肌肉試驗得出了以下結(jié)果：在低速累加器根本沒有回應。變壓力沒有顯著差異；在高速時累加器沒有回應。由于沒有從蓄電池整個系統(tǒng)的振動響應，使電線和增加穿越振動。在用張力傳感器搜集數(shù)據(jù)之前，蓄電池如圖8所示。最大和最小張力分別約為62N和46N。沒有累加器的1?詣電嫌線張力變化圖8：沒有累加器的張力傳感器的輸出有累加器的1■胡躍米線張力變牝0T13樣71-圖8：沒有累加器的張力傳感器的輸出有累加器的1■胡躍米線張力變牝0T13樣71-275232t29圖9有累加器的張力傳感器的輸出張力傳感器在使用時收集的累加器數(shù)據(jù)如圖9所示。最高和最低張力分別約為43N和37N。六?結(jié)論矩形線圈是配電變壓器的重要組成部分。由于線圈形狀，線圈的繞組線張力產(chǎn)生波動。這些波動導致電線破損，線圈尺寸不一致，多余的機器磨損，限制對卷繞速度和變壓器故障。從我們現(xiàn)有張力系統(tǒng)的研究，雖然發(fā)現(xiàn)流體肌肉累加器是最合適的選擇，但是不是非常滿足我們的要求。由于目前的張力系統(tǒng)，不是一個合適的補償接口，決定向扁平絲機的基礎上進行實驗和仿真。因此，平線中使用的氣瓶發(fā)生肌肉的機器成為可行性建議。新的繞線機將增加幾乎一倍當前卷繞速度，估計每臺機器每年可節(jié)省約59100美元。新的張力系統(tǒng)，可以達到到500N的恒張力，而不會產(chǎn)生大量的熱量，從而克服了當前摩擦的相關問題。參考文獻CaryStapleton,“WindingMachineTensionControl”，Dissertation,FacultyofEngineeringandSurveying,UniversityofsouthernQueensland,QLD,Australia,Dec.,2005K.Feldmann&D.Dobroschke,‘Innovativeapproachesforoptimisingtensioncontrol',InternationalCoilWindingJournal2004.K.Feldmann&U.Wenger,"Optimizationforwiretensioners',Proceedings:ElectricalManufacturing&CoilWindingAssociationConference.2001.T.Manning,"Tensioncontrolduringthecoilwindingprocess',Proceedings:ElectricalInsulationConferenceandElectricalManufacturing&CoilWindingAssociationConference,Apr.2005.J.Stangroom,"Tensioncontrol-newapproaches',WireIndustry59(697),33—3,1992.AnneAngermann,MaikAicher&DierkSchroder,“Time-optimaltensioncontrolforprocessingplantswithcontinuousmovingwebs”，2000IEEEIndustryApplicationsConferenceProceedings,pp.3505-3511,Wl5,Oct.8-12,2000,Rome,Italy.B.H.Freyer,I.K.Craig&P.C.Pistorius,“Gaugeandtensioncontrolduringtheaccelerationphaseofasteckelhotrollingmill,”ISIJInternational,Vol.43,No.10,pp.1562-1571,Oct.2003.BrainThomasBoulter,Y.Hou,Z.Gao&F.Jiang,“Activedisturbancerejectioncontrolforwebtensionregulationandcontrol,”2001IEEEConferenceonDecisionandControlProceedings,Vol.5,pp.4974-4979,Dec.4-7,2001,Orlando,FL,USA附件2:外文原文TensionControlofaWindingMachineforRectangularCoilsPengWenandCaryStapletonFacultyofEngineeringandSurveyingUniversityofSouthernQueensland
