| Summary: | The proper technical condition of a vehicle and rail track in operation is a key
aspect in terms of safety and travel comfort. This issue is of particular importance for
operators and managers of rolling stock and rail infrastructure. Currently, many diagnostic
systems have been developed to monitor the technical condition of selected vehicle systems
or rail track from the viewpoints of both the vehicle and track. This article proposes the use
of vibration signals in selected quantitative and qualitative analyses as the main diagnostic
parameter. For this purpose, over a dozen vibration measurements were carried out during
the normal operation of a freight wagon as part of a so-called passive experiment.
Measurement points were located on the axle boxes of the wheelsets. The proposed
research methodology served as a basis for comparative analyses of the selected
operational cases that were investigated. The most important conclusion from the study is
that it is possible to monitor the technical condition of vehicles and tracks in real time on
the basis of measurements of vibration accelerations at the vehicle level. This directly
increases the service life of rolling stock and optimises operating costs by changing the
maintenance strategy to one that takes into account the idea of modern on-board technical
diagnostics. Another important aspect is the possibility of the varied use of the proposed
measurement system, depending on the purpose of the research, which is also associated
with the diagnostician’s experience in processing vibroacoustic signals and the utilisation
of simple or complex quantitative and qualitative analyses. |
