Abstract:
The damage to a railway during high-speed movement of heavy trains in its various sections is modeled using a grid-characteristic method in the case of structured grids the damage process. The separation of sleepers from the ballast layer is studied. Computer simulation provided various wave patterns and patterns of dynamic distributions of the Cauchy stress tensor (pressure) components during train movement on a railway track. The cracking process is described.
Keywords:
grid-characteristic method, numerical modeling, wheel–rail system, wave phenomena, railway track.
