The non-linear 3D model of the rail seating

Original language description

The rail is placed on the seating and on the sleeper. The rubber pad is placed between the sleeper and the seating and also between the seating and the rail. The flat and rather stiff pad is for the electric isolation. To decrease the influence of forces(due to weight of the train) to the load of the sleeper and to the degradation of the gravely bed the use of massively softer pad with the contact protrusions is prepared. The layer system concrete sleeper - rubber pad - steel seating - rubber pad - rail is pre-stressed. This leads to the initial load of the seating. Under the train weight the load of the seating changes and the fatigue effect appears. The static analysis results from two load steps - the pre-stressed unloaded seating and the train weight load - are the inputs to the fatigue analysis.
