Parameters of the oscillatory process of the sleeper base in the area of the rail joint when using elastic spacers

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