Research On Line Device Unit Hierarchical Management Methods Of High-Speed Railway

With the increasing of high-speed railway operating mileage, the pressure of management and maintenance in Railway Bureau is getting bigger. It is need to rebuild the scientific management methods of track equipment urgently, this paper rely on "railway line unit quality balanced management system" of Wuhan Railway Bureau, and according to Wuhan-Guangzhou high-speed railway, and explore the applicability of the device unit hierarchical management approach in high-speed railway. The main work is as follows:1.With the fully research high-speed railway maintenance management current situation in domestic and foreign, and basis on analysis railway maintenance management problems and insufficient in our country, and discussion on the introduction of track equipment unit management in high-speed railway.2. It fully demonstrates the necessity of equipment unit division in high-speed railway. By comparing influencing factors in device unit division, and propose the main reference in device unit division, and analysis the method of device unit division specifically, on this basis, and discuss the dynamic partitioning method in device unit.3. On the basis of high-speed railway device unit division, fully analysis the characteristics of static and dynamic test data in high-speed railway management, then, according to the current high-speed railway management standards again overrun spreadsheet the track dynamic geometry detection data, and acceleration of the vehicle body with full peak according to foreign management experience, then, reset the test data management standards and assessment criteria based on device unit, determine comprehensive evaluation system of static and dynamic test data, and established the multilevel comprehensive evaluation model based on the device unit.4. Discussion on design ideas of how to build Track device unit management in "management、detect、repair". And based on device unit evaluation grade implement hierarchical management, then, combine device unit management with security production plan, and proposed device unit performance appraisal system.Wuhan-Guangzhou high-speed railway segment of Wuhan Railway Bureau tube instance verify the effect of terrestrial applications. Since the implementation of a few years, the quality of line equipment is increasing gradually, and annual comprehensive evaluation of line device unit fine rate remained at 100%, the dynamic test data almost have no III and IV level overrun, I and II level overrun significantly reduced throughout the year, The matching degree of motion detection and artificial static review is more than 95%, the effect is obvious.
