Abstract:It is very important and necessary for mechanical fault diagnostics to enrich and improve machine fault diagnosis technology. The prior information of the object as a constraint is integrated into the independent component analysis algorithm based on constrained dependent component analysis and the new algorithm converges only fault signal of interest in the paper. The relevance and effectiveness of fault diagnosis are improved. The method can find out rapidly whether there is a fault in mechanical equipment from sensor signals. The applicability and effectiveness of the method are verified by the simulation and experiment of roll element bearing.
