Abstract

To ensure the security of high speed railway, the basic principle of MFL detection was analyzed. The absolute peak value, the peak-peak value and the peak spacing are selected as the MFL signal features. The relationships between the defect geometry parameters and the MFL signal features are researched by simulation. The method of quantitative recognition defect based on RBF neural network was studied in this paper, and the experimental result shows that the method is feasible.
