Abstract: If intermittent fault is determined as permanent fault will cause needless shut down and excessive maintenance, make bad influence on operational readiness and waste maintenance support resource, put forward an intermittent fault diagnosis method. Analyze the influence of intermittent fault on system and technical difficulties of intermittent fault diagnosis, and summarize experts’ intermittent fault diagnosis methods at home and abroad. Then, introduce the further research of intermittent fault failure mechanism and evolution law, diagnosis models of intermittent fault and permanent fault and intermittent fault diagnosis method under extreme environment. The research provides reference for intermittent fault diagnosis, especially for intermittent fault diagnosis problem cause by extreme environment stress.
