Abstract:

Relay is widely used,so it is of great significance to study its reliability.The storage reliability evaluation and life prediction of relays are important contents of relay reliability research.The failure mechanism of relay under long-term storage is briefly described.The influence of various environmental stresses on the storage reliability of relay and failure mechanism are analyzed.The several methods of relay reliability evaluation such as genetic neural network model and Bayes method are introduced.These reliability evaluation methods are analyzed and described.The application of accelerated degradation experiment method and grey theory model in the field of relay life prediction are summarized.Finally,the research on how to carry out accelerated degradation test and life prediction for high reliability relay products is prospected.

Key words: relay, failure mechanism, accelerated degradation test, life prediction
