The invention discloses a classification method for five-level inspection and repair of city railway vehicles, which is characterized in that the method comprises the following steps: collecting status information of city railway vehicles; The state information includes the cyclical operation mileage information, the cyclical operation time information, the bogie, the vehicle body, the coupler buffer, the traction motor, and the state information of the filter part of the under-vehicle appliance. The state information includes the operation state information, the fatigue degree information, and the fault information. The fatigue information is compared with the pre-stored initial state information to estimate the estimated failure time. Cycle mileage information, cycle time information, analysis results and estimated failure time are comprehensively considered to determine to enter the first-level repair, second-level repair, third-level repair, fourth-level repair or fifth-level repair. The invention provides a five-level inspection and maintenance classification method for rolling stock according to the characteristics of the city railway, which ensures the safety and economy ofeach part.
Description
technical field [0001] The invention belongs to the technical field of urban railway maintenance, and more specifically relates to a classification method for five-level maintenance of urban railway vehicles. Background technique [0002] At present, the maintenance thought and system in the world can be divided into two major systems, one is the planned preventive maintenance system based on wear theory under the guidance of the "prevention first" maintenance thought; the other is the "reliability-centered" maintenance Under the guidance of ideology, the condition-based preventive maintenance system is based on the fault statistics theory. The maintenance system of EMUs can generally be divided into preventive maintenance and post-event maintenance. Among them, preventive maintenance can be divided into regular maintenance and condition-based maintenance. The maintenance of EMUs and subways can generally be divided into five levels, of which the first and second levels ar...
