The article presents the results of field tests of under-rail pads in order to assess the effect of stiffness and the number of standard and experimental rail pads-shock absorbers on the amplitude-frequency characteristic of vibrations that occur in the ballast layer in the rail joint zone when the rolling stock is moving. To achieve this goal, we measured the vertical vibration accelerations arising during the trains passage in the area of the rail joint with a different number of standard rail pads-shock absorbers CP-204-M-ARS (regular) and Getzner Sylodyn NF high resilience shock absorbers (experimental). On the basis of the obtained values, the amplitude-frequency characteristic of the oscillatory process was determined by means of the Fourier transform. The main (carrier) frequencies at which the maximum amplitudes of vibration accelerations are recorded, are determined, first of all, not by the damper pad material, but by the force effect magnitude. The use of experimental shock absorber pads makes it possible to reduce and redistribute the vibration energy transmitted to the ballast layer.
