Railway switch and crossing (S&C) systems have a very complex structure that requires not
only a large number of components (such as rails, check rails, switches, crossings, turnout …

The high-speed turnout is a key part of railway track infrastructure. A process of wheel-load
transition and single-wheel/multi-track contact take place in the turnout area, causing …

Switch and crossing (S&C) faults are a major cause of track-related delays and account for a
significant proportion of maintenance and renewal budgets for railway infrastructure …

This study evaluates the degradation of wheels and rails at railway crossings. The
evaluation method is composed of 1) finite element simulation of dynamic wheel/crossing …

During train operation, the geometric tolerance in a turnout can be very random, posing a
challenge for traditional deterministic vehicle-turnout coupling studies and for daily …

A dynamic 3D finite element model for the calculation of profile degradation in the switch
panel is presented. The model includes the contact between wheel and rail, as well as the …

The rail profile irregular variation and wheel-rail relationships complexity at the gap in the
frog enhance the wheel-rail impact forces, frequently resulting in rolling fatigue damage …

A numerical tool is proposed to simultaneously assess various damage mechanisms that
are driven by contact loading. The tool transfers loads to the contact-patch level using three …

In this study, the initiation of subsurface damage due to the impact of new and worn wheels
on differently deformed crossing nose geometries is calculated using the Dang-Van …

A finite element model is introduced to investigate the deformation mechanisms of
manganese steel crossings:(i) the plastic adaptation after installation and (ii) the long-term …
