FRACAS Based Failure Information Management for High-Speed Train

Abstract

Failure, because of the important role in the product life cycle for improving product design and manufacturing, is becoming important data information and being taken seriously. High-speed trains are complex electromechanical integration systems, and its failure occurred in operation may directly relate to people's life and property safety. FRACAS is a reliability engineering method, which allows the product fault information to follow Discovering, Report, Analysis,Correct andConfirm closed-loop management process, provides data and information to support effectively for improving the reliability of the train. This paper analyzed the fault information management needs of high-speed trains, combines high-speed trains product structure tree and fault model base to generate a high-speed train fault information database, by customizing and developing Relex FRACAS software. Then high-speed trains (CRH3) closed-loop management system is established. High-speed train FRACAS can easily build enterprise information platform for product reliability. Through the establishment of a unified failures database and solutions knowledge base, standardized information transferring and sharing are achieved. The train products faults can be timely reported and corrected. The accumulated data of troubleshooting in the whole process can be used in the failure statistical analysis and reliability prediction, which can effectively avoid major failures and repeated failures.
