| Abstract: | Fuzzy fault tree analysis is used to solve faults diagnosis in hydraulic system because of the multiformity of fault features, fault transmission in hydro circuits, complexity of hydraulic device construction. An example of pump controlled motor system is based on the principle, the method and the features of this method, which is described by analyzing its fault modes, constructing the fuzzy fault tree, making mathematics analysis of fuzzy fault tree and fault diagnosis algorithm research, etc. So it shows that this method is very effective and practice. |
