MODELLING OF VIBROACOUSTIC DYNAMICS OF SLEEPERS DURING ROLLING STOCK MOVEMENT
The article gives the results of studies of sleepers’ vibroacoustic characteristics. It is shown that the levels of sound emitted by sleepers are higher than the maximum allowable values. The relations for the calculation of noise and vibration spectra, taking into account the structural, physical and mechanical characteristics of sleepers and ballast bed and the speed of rolling stock movement are obtained.
