Abstract

For improving the reliability of Concrete pump, fault diagnosis is proposed based on the main oil hydraulic pumping system T-S fuzzy fault tree method. The proposed method used fuzzy numbers to describe the probability of failure of hydraulic components and systems to address the failure probability of uncertainty; described by T-S fuzzy door contact between events, to solve the ambiguity and failure mechanisms associated events; fuzzy numbers description of the problem severity, considering the effect of the degree of fault on the system. The method is applied to the fault diagnosis of pumping concrete main oil pump hydraulic system, and achieved good results.
