| Abstract: | Hydraulic power carts for aircraft is complex and has a high incidence of failure,the existing fault diagnosis method was simple,backward and low precision.A fault diagnosis expert system is developed for fault diagnosis of hydraulic power carts for aircraft,which combines fuzzy mathematic theory with expert system diagnosis method.This system can identify the cause of the faults quickly and accurately,used forward chaining inference mechanism based on knowledge base and comprehensive database,the results showed it greatly improved the efficiency and accuracy of the hydraulic power carts for aircraft fault diagnosis. |
