A Reliability Evaluation of High-Speed Railway Traction System Based on Failure Effect Analysis

Evelina Rakhmetova
The article presents the necessity to perform reliability evaluation of railway traction system with respect to the current status and plans for further development of high-speed railways in Russia. Basing on the statistical data provided on failures for various units of electric trains, the traction system was selected. A complex analysis of the traction system was carried out, and a model for the interconnection of system components was compiled. The reliability chart of traction system of

The calculation has resulted in a total failure rate of the system equal to 4,46% or 580 hours of suspended operation of the train. Also, the most vulnerable element of the traction system was identified-a traction system motor. Basing on these outcomes a set of recommendations has been made in order to increase the performance efficiency of the high-speed trains.
