| Abstract: | This paper introduces the applications and diagnosis effect of support vector machines (SVM) arithmetic in the field of fault diagnoses of hydraulic system. Taking fully hydraulic crane as research object and slewing circuit of the crane model as an independent system, it builds relevant mathematical model with power bond graph, and simulates the model with the Simulink of Matlab, at the same time does the characteristics of flux by selecting different parameters of the slewing circuit . Finally by adopting the SVM theory and according to the characteristics of fluxing value, it classifies the fault of the slewing circuit and gets a satisfactory fault class rate. |
