Modern Condition Monitoring Systems for Railway Wheel set Dynamics: Performance Analysis and Limitations of Existing Techniques

Delft University of Technology Condition monitoring approaches for the detection of railway wheel defects

Model-based Condition Monitoring for Railway Vehicle Systems

Although modelling techniques for railway vehicle dynamics are well-developed, much of the development in railway vehicle condition monitoring has relied on the knowledge-based techniques where no analytical system model is employed and only qualitative or empirical system knowledge are used for fault diagnosis. In this paper, the model-based approach is proposed as an alternative for railway v...

Wheel-Rail Profile Condition Monitoring

Increased railway patronage worldwide is putting pressure on rolling stock and infrastructure to operate at higher capacity and with improved punctuality. Condition monitoring is seen as a contributing factor in enabling this and is highlighted here in the context of rolling stock being procured with high capacity data buses, multiple sensors and centralised control. This therefore leaves scope...

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval

Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
