Fault diagnosis for Hydraulic hoisting system based on the probabilistic SDG model

摘要：

Focusing on the hoisting mechanism of crane hydraulic.. This paper gives the fault mechanism analysis and fault probability calculation method based on the probabilistic SDG model. The fault mechanism is described by the probabilistic SDG model while the fault propagation is presented by the conditional probability. And so the connection tree algorithm and figure elimination algorithm can be used in Bayesian inference to calculate the fault probability. In case of the given fault, the fault probabilities of the part components can be given.
