Abstract

In engineering practice, during the gradual development of many equipment from normal state to fault state, they have to experience the three-level working state of "safety state - potential failure - functional failure". From the external performance of potential failure, the first is that the symptom is weak, non-stationary, and does not cause substantial damage to the system. The detected data is zero-failure data, Therefore, the characteristic information of potential failure is relatively small, which belongs to typical small sample information; Secondly, due to the lack of accurate judgment and health analysis of equipment working state, the unnecessary maintenance may aggravate the evolution speed from potential failure to failure; Third, when the equipment operates under overload or harsh conditions, it will promote the deterioration of potential failure to a certain extent. Aiming at the difficulty of reliability evaluation of multi state system, a reliability method based on information fusion is proposed by making rational use of prior information, which provides a technical way for equipment reliability evaluation.
