Investigation of the oscillatory process in the railroad ballast, clogged sand dunes

Abstract

Investigation of the oscillatory process in the railroad ballast, clogged sand dunes

A special place to identify the characteristics of the oscillatory process of the ballast material, you need to take, first of all, the nature of the process fluctuations. Its identification contributes to the elucidation of their causes, it is important to assess the impact of fluctuations on the properties and condition of the ballast. Knowledge of the nature of the oscillatory process can continue to simulate it in the laboratory to determine the degree of reduction of the strength properties of the ballast material, clogged sand under the influence of vibrodynamic load, with the passage of rolling stock.

Keywords: Track bed, crushed granite, amplitude, oscillation, damping of oscillation, vibrodynamics
