Reliability prediction of electromechanical system concerned about correlation of multiple failures based on RFD

摘要

As the boosting complexity of developing electromechanical system in various fields,significant efforts have been recently devoted to the reliability analysis of electromechanical system to obtain better precision of reliability prediction,leading to advanced demand of reliability prediction methodologies.Conventional system rehability prediction adopts the reliability prediction theory of electronic products which ignores the interaction among different components.Aiming at this,an improved reliability calculation approach concerning correlation is proposed in this paper,taking dependence into account by considering the correlation degree between the primary and the secondary failure modes of components as the main factor in reliability prediction by building failure modes reliability prediction HOR(house of reliability)of components.
