The Impact of High-Speed Trains on Railway Infrastructure

Railway transport is now developing at a rapid pace. New trends in road construction can be seen as increasing train speed, increased axel load and the use of various types of fastenings. Studying the relationship between the elements of railway superstructure and their finite element modeling is one of the actual issues of our time in railway sphere.As far as we know, railroad construction is a high-priced transport system, and natural experiments are also associated with huge expenses.Taking into account the fact that 21st century is the century of information technology and the above given factors and the, it is advisable to use modern finite element analyze soft wares. Solving railway problems by using finite element analysis and simulating can save not only money but also time.In this thesis, we have modeled wheels, rails and sleepers using the Abaqus/CEO finite element software. The modeling was carried out by transferring a static load of 12.5 KN through the wheel. Then the load was moved to 2m and analyzed the track condition.
