Research on delamination fault diagnosis of marine diesel engine based on Support Vector Machine

In this paper, the authors introduce the principle and algorithm of the support vector machine, the hierarchical analysis and the application of hierarchical analysis to fault diagnosis. In the above-mentioned theory, the paper presents a fault model of the marine diesel engine, and focuses on the application of Support Vector Machine (SVM) on fault diagnosis of marine main engine cooling system. The simulation result shows that SVM has good diagnosis effect in small samples as well as good application prospects in mechanical fault diagnosis.
