Operational Reliability Analysis for the Rolling Bearing of Bogie in Urban Rail Train

摘要：

　　Rolling bearings of bogie in city rail train play an important role in operation safety.The operation reliability PHM for rolling bearings of bogie is designed,based on a general idea including data acquisition,covariate selection and calculation,model hypothesis testing and parameter estimation.Aiming at the problem of complexity and difficulty of parameter estimation of multi-parameter WPHM,constriction factor PSO algorithm is modified to realize faster convergence of the parameter estimation.Finally the numerical example shows that this method is reasonable and efficient.
