Wheel-rail profile real-time estimation techniques and challenges

conference contribution

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 for advanced computational diagnostic concepts. The rail vehicle bogie and associated wheelsets are one of the largest and most costly areas of maintenance on rolling stock and a potential method is presented here for real time estimation of wheel-rail contact wear to move this currently schedule-based assessment to condition-based assessment. This paper discusses several analytical techniques used to capture the wheel-rail geometry characteristics in real time.
