Wheel Monitoring System (WMS)

Reduce noise of vehicles and maintenance costs

The WMS is designed to monitor wheel tread damages as polygons and flats and their evolution. It grants:

  • early detection of wheel polygons
  • early detection of wheel flats
  • increased safety
  • noise and vibration reduction
  • reduction of complaints from residents
  • condition based maintenance
  • cost saving from less maintenance and higher runtime of wheel sets
  • vehicle information (ID, speed, etc.)

The WMS identifies the passing vehicle, analyses the wheel tread quality, stores the results to a databank and provides reliable, fast and plain results on

  • wheel conditions within the monitored rail fleet,
  • spread of wheel damages
  • the development of wheel damages

The large datasets collected by the WMS support statistical analyses on identifying root mechanisms. The following parameters can be measured by the Wheel Monitoring System:

  • wheel tread defects (e. g. flats, etc. [EN 15313])
  • wheel tread polygonization [UIC B 169/DT 405], [EN 15313]

The most important characteristics of the WMS are:

  • fully automated operation
  • high measurement accuracy with high repeatability
  • fast and easy installation of the system
  • vehicle identification module
  • noise measuring and monitoring module
  • graphical user interface provided by the software
  • simple and easy to use
  • product is guaranteed to be supported for at least 10 years

Technical principle
Quick, robust and non-invasive installation in the track. Specifically designed WMS sensors measure the wheel tread condition of each passing wheel (i.e. detecting flats, polygons). A vehicle identification system registers the vehicle and its numbers. Optional microphones capture the noise emissions (i.e. detecting malfunctioning aggregates).

Precise and comprehensible results: WMS processes all wheels and yields indicators for polygonisation and flats. The displayed indication is proportional to the severity of the damage / polygonisation and may additionally be adjusted to the customer’s needs.

Option: Mobile Wheel Monitoring System (WMS)
The mobile WMS temporarily offers the benefits of a fully automated WMS at an attractive price and an even reduced installation time. It is best used to quickly assess the quality of wheel tread conditions across the entire fleet.
