“…In particular, conventional nondestructive evaluation (NDE) methods are known to be difficult to apply for the foot area of the switch rail. [2][3][4][5] In addition, the closed operation mode is adopted during the day, 6 while the detection and maintenance of the railway can only be performed at night. There is thus little time available for the on-the-spot inspection of the switch rail.…”

“…From Figure 11 we can see, the result of 2D-FFT coincides well with the frequency wavenumber curve of the corresponding mode and there is no interference mode. The wavenumber ξ and frequency f are substituted into Equation (10). The calculation results of simulated phase velocities are shown in Table 4, and compared with theoretical values.…”

“…In the research of rail defect detection based on guided waves, some scholars selected the suitable modes for rail defect detection by a mode classification method. Hayashi [10] divided the modes of the rail base into three categories. By analyzing the dispersion characteristics of guided waves, the concept of dominant modes is proposed.…”

“…Rail Dispersion is a specially developed software for calculations of rail dispersion curves and wave structures, as shown in Figure 3. 101 Cross sections of various shapes can be drawn by the CAD and input in the Rail Dispersion as a DXF file. Then, GiD software can be adopted to generate the cross-section mesh.…”
