飞机机轮径侧向压力自动检测系统论文.doc

摘要随着航天事业的快速发展为了提高飞机的运行稳定性和安全性需要对各种飞机机轮进行静态力学性能测试。以验证机轮在最大静载荷和最大限制载荷下的承受能力。目前国内现有的两台径侧向机轮试验台都研制于二十世纪七十年代绝大部分的仪器仪表都是模拟的不方便控制和观测且载荷试验都必须手动完成已经不能够满足当前对飞机机轮进行的静态力学载荷性能试验的要求了。因此研制一台高性能的全数字化的径侧向机轮试验台并采用先进的控制算法具有十分重大的意义。该试验装置由液压系统、电气控制两部分组成本文的任务是完成试验台电气控制部分的研制与调试。本文就该试验台的电气控制部分的系统设计、硬件选型、硬件电路实现、软件设计做出了详细介绍。最后进行了系统的实验室调试将系统不断完善、本文的重点是介绍系统的硬件设计和软件设计对系统的软件、硬件做了详细的阐述。在实际应用中系统的可靠性和稳定性得到了很好的验证采用PID控制算法通过现场调试取得了较好的控制效果。关键词机轮径侧向工控机可编程逻辑控制器组态软件PID控制ABSTRACTWiththedevelopmentofthespacetechniqueweneedtotestavarietyofairplanetyresforstaticmechanicsperformanceforenhancingthestabilityandsecurityoftheairplane.Whiledesiningthenewairplanetyrethetestofthesiddirectionofthefoot-pathmustbecarriedoutinordertoprovetheadaptabilityoftheairplanetyreunderthegreatestquietloadandthegreatestrestrictionload.Sincethetwocenturychinainthe1970smostoftheapparatusareanalogapparatuswhicharemadethecontrolandobservingtestinginconvenient.Thusdevelopedahigh-performancecombinedradialandsideloadtestmachinehasgreatsignificance.Theobservingandcontrollingplatformiscomposedbythehydraulicpressuresystemandelectricalair.Thetaskofthistextistofinishstudyinganddebuggingthepartoflaboratorybench.Thistestpresentsthesystematicdesignselcectinghardwaretyperealizinghardwarecircuitanddesigningsoftwareofelectriccontrolsystemsindetails.Finallycarriyonthesystematiclaboratoryandsystematicdebuggingonthespot.Thefocalpointofthetextisthedesignofthesystematichardwareandsoftware.Thearticleaddressesthesystem’ssoftwareandhardwareindetails.Inthepracticaltestsystem’sreliabilityandstabilityhasbeenproved.ControlalgorithmsbasedonPIDcontrolthroughthedebuggingpressurecontrolachievedgoodresults.KEYWORDStheaircraftwheel’sradialandlateraldirectionindustrialcontrollingcomputertheprogrammedlogiccontrollerconfigur
