基于ANN求导的DSFT中故障概率变化趋势研究
Research on method for trend of failure probability in DSFT based on ANN derivation
摘要
Abstract
In order to take measures in advance control element failure before coming bad work environment,this paper put forward the method of determining the changing trend of component failure probability based on ANN derivation.Without the composition and nature of system or component,and only with the actual fault monitoring data,this method could understand the trend and changing degree of system or component in different working conditions.The method also enriched the theory of the discrete space fault tree(DSFT) in the framework of space fault tree.It presented the theoretical basis and the derived formula with ANN derivation.Combined with a component for the application of the proposed method,it obtained the change tendency of the failure probability distribution finally.It provided the reference to adopt measures to prevent failure in advance in the process of production.关键词
