Slab Track

Objective

This research will study the performance of floating-slab tracks both numerically and experimentally

Background

Studying the dynamics of railway tracks is important in order to improve their behavior. The dynamic behavior of railway tracks affects the ride quality of trains (including the level of noise and vibration perceived by passengers). It also affects the stability of trains and the structural integrity of the tracks and their supporting infrastructure. Furthermore, it influences the levels of noise and vibration transmitted to nearby buildings.

There are two types of railway tracks; ballasted tracks and slab tracks. Slab tracks are used in a large number of cities around the world. In comparison to ballasted tracks, they are known to require less maintenance. In this work, the slab track dynamics and the interaction between track components are going to be modeled using wave-number domain approaches for the tracks with continuous slabs and the periodic-infinite structure theory for tracks with discrete slabs. Both bending and torsional behaviors will be investigated and checked against Finite Element results. The numerical models will be validated by experimental measurements using Qatar Rail mockup railway tracks.
