1. Analytical models of LRS behavior
To approach a study of welded long rail (CWR) systems and the problem of rail-structure interaction (RSI), it is first necessary to return to classical questions of track mechanics, so as to be able to apprehend interaction models under thermal loading or any other loading.
Running track" refers to the system of rails, sleepers and fasteners, laid directly or via ballast, with no special zones such as switches, changes in rail cross-section, changes in shunting, engineering structures or tunnels, etc. It is the most common part of the railway. This is the most common part of the railroad.
In fact, the track laying method will have a major influence on the track's resistance, and will come into play from its behavioral law. On a high-speed line with a variety of fastening methods, it would be wise to distinguish...
