%X According to the characteristics of complicated structure as well as fuzzy failure probabilities, mechanism and degree of the hydraulic system of concrete pump truck, this paper proposed a fault diagnosis method of hydraulic system based on T-S fuzzy fault tree analysis. This method described failure probability of hydraulic components and system with fuzzy numbers, solved the problem of uncertainty of failure probability. It described connection between events using T-S fuzzy gate, solved the problem of fuzziness of connection between failure mechanism and events. It described failure degree with fuzzy numbers, considered the influence of failure degree on system. Applications of this method in fault diagnosis of hydraulic system are introduced in combination with an example of failure analysis of hydraulic system.
