A Literature Survey on Condition Monitoring Techniques for Wheel Flat Detection
The skidding of the wheel tread leads to severe localized wear in the wheels i.e. wheel flat. Presence of wheel flats generate impact load and vibration. The wheel flat is one of the many issues causing severe rail stress and sometimes derailment due to rail fracture. Therefore, it is necessary to monitor impact load due to wheel flat. This paper aims to give an overview of the existing condition monitoring techniques, such as on-board and way-side techniques, for detection of wheel flat at an early stage.
