Abstract

The relay is responsible for the power distribution and logic control function of the EMU. The failure of the relay affects the reliability of the system. Moreover, its failure often leads to the failure of important equipment or loops on the EMU, resulting in reduced speed operation or even shutdown, affecting the order and safety of driving. Systematically carry out work with inherent problems of the manufacturer analysis based on FMEA (Failure Mode Effects Analysis) using RPN (Risk Priority Number), provide support for effective life assessment and design selection.
