Course Contents
In this course the students will get deeper knowledge (as compared to the basis course on Elements of Railway Engineering CIE4874) on the static/dynamic behaviour and design of railway tracks.

Starting from learning the main principles of railway track and railway vehicle the students will get acquainted with the modern analytical/engineering and numerical methods (Finite Element and Multi-body based computer software e.g. Longstab and VI-Rail) for analysis and design of railway tracks.

In order to get acquainted with novel railway systems an excursion to manufacturer of elastomer for Embedded Rail Structures Edilon)(Sedra is planned.

At the end of the course, the students have to apply the gained knowledge to solve a given real-life railway track related problem (e.g. improve design or/and performance of existing track).

The course consists of 3 parts.

Part 1 (Dr V. Markine, V.L.Markine@tudelft.nl)

In this part the track behaviour will be analysed on the level vehicle - track interaction.
The basic principles of railway track and vehicle design will briefly introduced here (for more information the course CIE4874 Elements of Railway Engineering is advised)
Analytical and numerical methods for analysis of the static behaviour of a railway track will be explained. Also engineering methods to access the dynamic effects will be introduced.
Analysis of stresses in the track element and a result of and temperature forces.
Assessment of the track behaviour and selection of the track components.


Part 2 (Dr M. Steenbergen, M.J.M.M.Steenbergen@tudelft.nl)

In this part the dynamic principles of the track structures will be discussed:

The equation of motion; Degrees of freedom
Static versus dynamic design
Frequency Transforms
The dynamic stiffness
Rolling Contact types in Dynamics
Noise & Vibrations

Part 3 (DR Z.Li, z.li@tudelft.nl)

This part concerns some advanced aspects of vehicle design and wheel-rail interaction:

Vehicle design: vehicle-track interaction, dynamic load and ride comfort (including practicum with numerical simulations)
Basics of contact mechanics for wheel-rail interaction analysis: contact patch, contact forces/stresses, rail damage mechanism
Study Goals
