A STUDY OF THE SPECIALIZED FMEA PROCEDURE FOR THE RAILROAD VEHICLE

초록

This study investigates the Failure Mode and Effect Analysis (FMEA) Method for the railroad vehicle. Recently, RAMS (Reliability, Availability, Maintainability and Safety) is one of the most important issues in the railroad industry. FMEA is a necessary for the RAMS Analysis. FMEA is a procedure for the analysis of a system to identify the potential failure modes and their effects and to reduce or mitigate the critical effects of the system. FMEA is used in various industries and it is specialized in each industry. For instance, MIL-1629a in Military industry, SAE-J1739 in Automotive industry and other industry are using specialized FMEA method. The railroad industry requires the high reliability system, but it does not have the FMEA method which is specialized to them. So in this paper, we study and propose the FMEA method that is specialized to the railroad vehicle due to analyze and compare the MIL-1629a, SAE-J1739, IEC-60812 standard.
