Fault Diagnosis to Mid-size Excavator Bucket Hydraulic System Based on Fault Tree Analysis

摘要：

　　Analyzes bucket hydraulic system of hydraulic excavator by fault tree analysis.According to logical relationship of hydraulic system structure, draws fault tree, finishes qualitative and quantitative analysis.Divides the minimum cut sets.Calculates the reliability of whole system to find the weakest components.Puts forward ways to increase the reliability on basis of oil pipe.
