Abstract :
The fault tree analysis method based on bond graph for feed water pump is introduced in this paper. Using a knowledge representation of bond graph modeling, which includes system structural, functional and behavioral information and there relation, fault tree based cause-effect reasoning is created by assigning qualitative value of parameters. Multiple fault hypotheses is employed to simplify branches of fault tree. The simulation demonstrates that the bond graph fault diagnosis method is effective, corrective and flexible.
