Software for evaluation of response signals measured on the rail fastening.

Software

It is going about the software for evaluation of response signals measured on the rail fastening. The analysis was supplemented with pictures that are created by three graphs (Fig. 4). The time behavior of the vibration response is shown in the upper picture. The left graph shows the amplitude spectrum of the vibration response depending on the frequency calculated by the application of the Fourier transformation to the signal measured. In the middle graph is the 3D presentation of the time-frequency behavior of the amplitude spectrum of acceleration. The values of the acceleration in the decibel scale are presented in the middle graph by different colors.
