The model consists of a moving wheel on a discretely supported rail.
Her "Sasa Clock" uses an installation of colored beads around a moving wheel to show the time.
This work presents a bench test designed to experimentally monitor and measure the forces transmitted to the ground by a moving wheel.
The process feeds molten metal through a nozzle onto a moving wheel where a puddle is formed and from which a continuous ribbon is 'spun'.
Wheel rail interaction is modelled on a non-linear Hertzian spring, and consideration is given to parametric excitation caused by the wheel moving over a sleeper, since this is a moving wheel model and not a moving irregularity model.
The wheel tracking test is capable of generating the maximum shear stress and the maximum bending stress that occur when a moving wheel is either slightly offset from or directly over a crack, respectively.

Up to now various methodologies have been applied based on the surface deflection bowl obtained under either a known moving wheel load or devices such as falling weight deflectometer.
The moving train is simulated by a sequence of moving wheel loads that may vibrate with certain frequency.
The other models were tested for fatigue strength using moving wheel load to derive a reliable fatigue formula.
The results are compared with those from a moving irregularity model and the differences between the moving wheel and moving irregularity models are examined from various aspects of wheel/rail dynamics.
Parametric excitations due to the moving wheel periodically passing the discontinuous slabs contribute significantly to the wheel/rail interactions.
