Motor train unit wheel set safety management method

Abstract

The invention discloses a motor train unit wheel set safety management method which includes the following steps of (1), establishing a motor train unit wheel set fault relational database; (2), performing magnitude maintenance for a wheel set; (3), performing interaction between a magnitude maintenance layer and a job control layer; and (4), performing information management to equipment. According to the method, information isolated islands of all layers can be broken, various data can be interconnected, and data management can be effectively carried out, so that safety and reliability of the motor train unit wheel set are guaranteed, and safe and reliable running of the motor train unit wheel set is realized.

Description

technical field [0001] The invention belongs to the field of EMU maintenance and detection, and in particular relates to a safety management method for EMU wheelsets. Background technique [0002] The running part is a key part of the railway train, which can ensure that the train runs flexibly, safely and smoothly along the rails and passes through the curve; and reliably transmits various forces on the EMUs to the rails, easing the mutual impact of the EMUs and the rails, and reducing the impact of the EMUs on the rails. Group vibration ensures sufficient running stability and good running quality. Therefore, the quality of the running part is directly related to the safety of train operation. [0003] As the key part of the running part, the wheel set is the final force-bearing part of the EMU operation, which mainly includes wheels, axles and bearings. Under high-speed running conditions, the wheels are prone to surface degradation, internal defects, and wheel out-of-ro...

AI Technical Summary

Problems solved by technology

[0006] At present, there is no systematic management method for EMU wheel sets, there are differences in the understanding of various grass-roots stations, management and maintenance personnel have inconsistent levels of information input and analysis, and the accumulation of basic data is not enough

There is no data exchange between different information systems at all levels, resulting in information isolation, which is not conducive to the life management of the wheel set, and there are many problems: difficult information exchange, difficult data recording, difficult wheel pair matching, etc.
