Study on Fault Diagnosis for the Forklift Hydraulic System Based on Fuzzy Tree Analysis Method

Fault tree analysis method was used to forklift hydraulic system fault diagnosis.According to failure modes and failure mechanism of the hydraulic system,the fault tree was built,and failure analysis and exclusion was carried out.Practice proves that the fault tree analysis method is easy,reliable and practical.Anticipative results can be achieved when it is used to diagnose hydraulic system fault.
