ASTFABSS 方法及其在齿轮箱复合故障诊断中的应用
ASTFABSS Method and Its Applications in Composite Fault Diagnosis for Gearbox
摘要
Abstract
Considering ASTFA method for decomposing the least number of single component as the optimization goal,and taking the physically meaningful instantaneous frequency of single compoG nent as constraint conditions,to make the components more reasonable,combining BSS,a BSS methG od was proposed based on the ASTFA,which was used to carry out composite fault diagnosis of the gearbox.In this method,the singlechannel source signals were decomposed by AFTFA,then the dominant eigenvalue method was used to estimate the number of sources,and observed signals were restructured by the number of sources,finally the estimation of source signals was obtained through BSS.The experimental results show that the proposed method can separate the composite fault signal of the gearbox effectively,and achieve the composite fault diagnosis of the gearbox.关键词
