Therefore, on the premise In view of the problems of over-maintenance and of ensuring train safety and the performance of tasks, reducing under-maintenance in the current urban rail transit maintenance the cost of vehicle maintenance has become an important strategy and the reliability of single processing of fault data, research topic in recent years. which is often inconsistent with the actual situation, an At present, the main maintenance modes of metro vehicles incomplete preventive maintenance strategy based on the are fault maintenance and periodic maintenance, in which the competitive Weibull model is proposed in this paper. To make maintenance effect is considered to be complete maintenance, the fault mechanism processing method for urban rail vehicles that is, "repair as new".
