数控机床故障的诊断研究中英文翻译NcmachinetoolfaultdiagnosisresearchinbothChineseandEnglishtranslation[摘要]故障诊断技术已经有30多年的发展历史,但作为一门综合性新学科《故障诊断学》,还是近些年发展起来的。从不同的角度出发,设备故障诊断的理论和方法很多,其中故障诊断专家系统方法是近年来故障诊断领域最显著的成就之一,其内容包括诊断知识的表达、诊断推理方法、不确定性推理及诊断知识的获取等。[abstract]:faultdiagnosistechnologyhasahistoryofmorethan30yearsofdevelopment,butasacomprehensivenewsubject,diagnosticsoffaultisdevelopedinrecentyears.Fromadifferentperspective,equipmentfaultdiagnosistheoryandmethodaremany,thefaultdiagnosisexpertsystemmethodisoneofthemostsignificantachievementsinfaultdiagnosisfieldinrecentyears,itscontentincludingdiagnosisknowledgeexpression,diagnosisreasoningmethod,uncertaintyreasoninganddiagnosisknowledgeacquisitionetc.[关键词]数控机床故障树分析[keywords]ncmachinetoolfaulttreeanalysis一、数控机床故障的诊断研究意义所在A,numericalcontrolmachinetoolfaultdiagnosisresearchisallabout故障诊断始于机械设备故障诊断,主要指制造设备和制造过程的状态监测与故障诊断。制造设备主要指加工机床、夹具、量具和刀具;制造过程指制造工艺过程、工艺参数。机械设备运行时的状态监测与故障诊断包含两方面内容:一是对设备的运行状态进行监测;二是在发现异常情况后对设备的故障进行分析、诊断。Faultdiagnosisbeginswithmechanicalequipmentfaultdiagnosis,mainlyreferstothemanufacturingequipmentandmanufacturingprocessofconditionmonitoringandfaultdiagnosis.Manufacturingequipmentismainlyreferstotheprocessingmachinetools,fixtures,measuringandcuttingtools;Manufacturingprocessreferstothemanufacturingprocessandprocessparameters.Conditionmonitoringandfaultdiagnosisofmechanicalequipmentruntimecontentcontainstwoaspects:oneistotheequipmentrunningstatusmonitoring;2itisafteranomalieshavebeenfoundtoequipmentfaultanalysisanddiagnosis.设备故障诊断是随设备管理和设备维修发展起来的。欧洲各国在欧洲维修团体联盟(FENMS)推动下,主要以英国倡导的设备综合工程学为指导;美国以后勤学为指导;日本吸收二者特点,提出了全员生产维修(TPM)的观点。Equipmentfaultdiagnosisisdevelopedalongwiththeequipmentmanagementandequipmentmaintenance.EuropeancountriesintheEuropeanUnionformaintenancegroup(FENMS),whichmainlyguidedbytheBritishadvocatecomprehensiveequipmentengineering;AfterstudywiththeguidanceintheUnitedStates;Japanabsorptioncharacteristicsbetweenthem,andputforwardthetotalproductivemaintenance(TPM)pointofview.美国自1961年开始执行阿波罗计划后,出现一系列因设备故障造成的事故,导致1967年在美国宇航局(NASA)倡导下,由美国海军研究室(ONR)主持成立了美国机械故障预防小组(MFPG),并积极从事技术诊断的开发。美国诊断技术在航空、航天、军事、核能等尖端部门仍处于世界领先地位。SincetheApolloprogrammestartedin1961intheUnitedStates,appearaseriesofaccidentscausedbyequipmentfailure,leadtotheNASA(NASA)in1967,underthesponsorshipbytheU.S.navalresearch(ONR)hostformedthemechanicalfailurepreventiongroup(MFPG),andactivelyengagedinthedevelopmentofdiagnosistechnology.Thediagnosistechnologyinaviation,aerospace,military,nuclearandothercutting-edgedepartmentisstillintheworldleadingposition.英国在上世纪60-70年代,以机器保健和状态监测协会(MHMG&CMA)为最先开始研究故障诊断技术,在摩擦磨损、汽车和飞机发电机监测和诊断方面具领先地位。UKinthelastcentury60s-70-s,inordertomachinecareandstatemonitoringassociation(MHMG&CMA)asthefirstbegantostudyfaultdiagnosistechnology,thefrictionandwear,carsandaircraftgeneratorm...
