流体技术舞蹈手臂肌肉：低速的手臂最初有反应，但在时间过长便急剧抽搐，如预期的一样不均匀地运动。导线似乎比没有手臂肌肉震动更剧烈。第一层的绕组已经从最初的地方向内约300毫米。在高速时手臂没有回应，只是均匀的立场振动。流体肌肉蓄电池技术：动力蓄电池的肌肉试验得出了以下结果：在低速累加器根本没有回应。变压力没有显着差异；在高速时累加器没有回应。由于没有从蓄电池整个系统的振动响应，使电线和增加穿越振动。在用张力传感器搜集数据之前，蓄电池如图8所示。最大和最小张力分别约为62N和46N。没有累加器的1・诣電嫌线张力变化图8：没有累加器的张力传感器的输出有累加器的1■胡躍米线张力变牝0T13样71-图8：没有累加器的张力传感器的输出有累加器的1■胡躍米线张力变牝0T13样71-275232t29图9有累加器的张力传感器的输出张力传感器在使用时收集的累加器数据如图9所示。最高和最低张力分别约为43N和37N。六•结论矩形线圈是配电变压器的重要组成部分。由于线圈形状，线圈的绕组线张力产生波动。这些波动导致电线破损，线圈尺寸不一致，多余的机器磨损，限制对卷绕速度和变压器故障。从我们现有张力系统的研究，虽然发现流体肌肉累加器是最合适的选择，但是不是非常满足我们的要求。由于目前的张力系统，不是一个合适的补偿接口，决定向扁平丝机的基础上进行实验和仿真。因此，平线中使用的气瓶发生肌肉的机器成为可行性建议。新的绕线机将增加几乎一倍当前卷绕速度，估计每台机器每年可节省约59100美元。新的张力系统，可以达到到500N的恒张力，而不会产生大量的热量，从而克服了当前摩擦的相关问题。参考文献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
