/一、动车组的维修特点02BasicmaintenancemodeofEMU基本维修方式0201032.BasicmaintenancemodeofEMU/二、基本维修方式Maintenancemodereferstothecontrolofequipmentmaintenanceopportunity.维修方式是指对设备维修时机的控制。Thetimingofmaintenanceisachievedbyadoptingdifferentmaintenancemethods.也就是说对维修时机的掌握是通过采用不同的维修方式来实现的。Timebasedmaintenance(alsocalledplannedmaintenance)定期维修（又称计划修）Condition-basedmaintenance(alsocalledcondition-basedmaintenance)视情维修（又称状态修）Run-to-breakdownmaintenance(alsocalledfaultmaintenance)事后维修（又称故障修）1．Timebasedmaintenance定期维修Timebasedmaintenanceistousethetimeormileageasthemaintenanceperiod.Regardlessofitstechnicalstatus,aslongastheuseofequipmenttothepre-specifiedtimeorrunningmileage,tocarryouttherequiredmaintenance,itisamandatorypreventivemaintenance.以使用时间作为维修期限，只要设备到了预先规定的时间，不管其技术状态如何，都要进行规定的维修工作，这是一种强制性的预防修理。ThekeyproblemofTimebasedmaintenanceliesinthedeterminationofmaintenancecycle定期维修的关键是如何确定维修周期Therighttimetorepairshouldbetheendoftheaccidentalfailurephase,thatis,beforethefailurerateintothewear-and-tearfailurephaseofthesharprise.正确的维修时机应该是偶然故障阶段的结束点，即在故障率进入耗损故障期急剧上升之前。keyproblem关键问题Howtodeterminethemaintenancecycleormaintenancetiming如何确定维修周期或维修的时机2.BasicmaintenancemodeofEMU/二、基本维修方式TheimplementationofTimebasedmaintenanceisguaranteedbytheplannedrepaircycle,repairlevelandscope,andtherelevantmaintenanceregulations.定期检修的实施是由计划修理周期、修理级别和检修范围以及有关的检修工作条例来保证的。AccidentalfailureperiodrepaircycleTimeEffectivelifeEarlyfailureperiodFailurerateRegulationfailurerate2.BasicmaintenancemodeofEMU/二、基本维修方式2.Condition-basedmaintenance视情维修Continuous,indirectorperiodicmonitoringofequipmentparametervaluesandtheirchangestodeterminethestatusofequipment,detectperformancedegradation,andlocateitsfaultsandfailurelocations,aservicethatrecordsandtrackstheprocessandtimeoffailure.对设备参数值及其变化进行连续、间接或定期的监测，以确定设备的状态，检测性能下降，定位其故障和失效部位，记录和追踪失效的过程和时间的一种维修。2.BasicmaintenancemodeofEMU/二、基本维修方式大量的故障不是瞬间发生的，而是有一个从发生到发展，最后形成故障状态的过程，总有一段出现异常的时间，而且有征兆可寻。因此如果找到跟踪故障迹象过程的方法，将观察到的设备运行状态和规定的标准进行比较，则可以采取措施预防故障发生或避免
