On The Evaluation Of Wheel Sets And Railway
Track Quality
Author(s)

Abstract
The cost of maintenance and the safety of railway operation depend (among
other things) on the quality of the wheel sets interaction with the rails. There is
the necessity to monitor the rolling behaviour of regular vehicles. Of most
importance is the time behaviour of the travelling contact forces between the
wheel sets and the trucks. The rolling wheel set obtains a very different position
relative to the track, which creates restraints in the wheel set and the track panel
structure, and which will discharge continuously by friction induced vibration.
Those vibrations cause corrugation, ballast deterioration, wear, squealing noise
and other environmental impacts.
Keywords: wheel sets, railway track, monitoring, motion, rolling performance,
system dynamics.
1 Introduction
There is the necessity for monitoring the rolling behaviour, because from the
determination of the geometrical track irregularity measurement, no prediction of
the rolling behaviour seems to be possible. Also the environmental impact
(vibration, noise) and the recurrent maintenance needs of pavement, sleepers and
rails depend strongly on the surpassing traffic, causing interaction between the
vehicle and the track and creating its specific \“footprint”.
Keywords
wheel sets, railway track, monitoring, motion, rolling performance,
system dynamics.
