A Study of Failure Mode, Effects and Criticality Analysis Process for the Railroad System

초록

This study investigates the Failure Mode, Effect and Criticality Analysis (FMECA) Method for the railroad vehicle. Recently, RAMS (Reliability, Availability, Maintainability and Safety) is one of the most important issues in the railroad industry. FMECA is a necessary for the RAMS Analysis. FMECA 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. FMECA 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 FMECA method. The railroad industry requires the high reliability system, but it does not have the FMECA method which is specialized to them. So in this paper, we study and propose the FMECA method that is specialized to the railroad vehicle due to analyze and compare the MIL-1629a, SAE-J1739, IEC-60812 standard.
