Job description
Short pitch rail corrugation is a type of vertical periodic irregularity on top of railway rails with a wavelength of 2-8 cm. It is a result of the dynamic interaction between the wheels and rails and is one of the major types of damage in most rail systems worldwide. It causes large dynamic contact forces, resulting not only in damages to rolling stock, wheel and rail, but also in rapid deterioration of track quality and noise nuisance, leading to high maintenance and renewal costs and reduced track availability. With the continuous increase in rail transport in the foreseeable future, the problem will be even more pronounced, particularly for networks which are approaching or have reached their capacity limit.
By means of numerical analyses, field monitoring and lab tests, this research aims at a fundamental understanding of the initiation and growth mechanisms of short pitch corrugation, basically the wavelength fixing mechanism and the damage mechanism by wear and plastic deformation. This should finally lead to improved track design to avoid corrugations, possible methods for detection of corrugation root causes in existing track, and action criteria for optimal maintenance. For this research, the Road and Railway Engineering Section at TU Delft is looking for a motivated PhD student.
