Nanjing Metro Vehicle Maintenance Repair Process Analysis And Optimization

The basic vehicle maintenance of metro rail transit vehicles using traditional maintenance mode, though with the new technology in vehicles and vehicle maintenance in constant use, maintenance cycle has been extended, but the whole system is based on vehicle maintenance vehicle mileage and certain time intervals, "prevention programs repair" and train failure "after the fault repair." Nanjing subway breakdowns in the realization of computer management and repair of major components on the basis of the state, the pilot will focus on Metro vehicles out of service into the daily maintenance of a balanced way of maintenance. To train for the job object to convert to the vehicle system components for the job object, use the train window time will focus on the maintenance of the contents of the arrangement in a few hours to complete, so that maintenance work on vehicles distributed by the centralized maintenance of a balanced number of maintenance at. Nanjing Metro analyzed the failure statistics for many years running condition of vehicles, overhaul of the original project cycle be shortened and extended, on the maintenance of repairs carried out to further optimize the combination of content to make it more consistent with the actual maintenance needs of metro vehicles. To achieve in ensuring the quality of vehicle maintenance and train operation under the premise of improved reliability, reduced maintenance of the train stopping time and improve train availability and rates and put into operation, to achieve the vehicle maintenance cost, quality, efficiency and optimization, to achieve good economic and social benefits.
