@ PHOENIXMos I Wheel Impact Load Detection

Diagnosis of Wheel Defects and Vehicle Weights Growing rail traffic worldwide requests higher safety standards and lower

maintenance cost at the same tirne. An essential aspect is a continuous, trustworthy

monitoring of interaction forces between the rolling stock and the infrastructure.

Wheels of rail vehicles are exposed to high wear and tear. This may result in

geometric wheel defects. The functions Wheel Defect Detection (PHOENixwoo)

and Weighing in Motion (PHOENIXw1M) allow for economic, reliable and

continuous supervision of wheel-rail interaction forces during normal train

operation.

Besides detecting wheel defects the functions are used as a dynamic rail scale at

the same time; vehicle weight and load distribution are monitored during every

passage and an unbalance or overload can be recognized in time. Assistance for

optimal payload usage is available as well.

Reliable Measurement Results Through Innovative Fibre Optic Technology

Forces induced by the wheel into the rail are captured by optical sensors clamped

under the rail. At a high scanning rate the deformation of the rail is measured.

Every wheel is identified during a train passage and data reports on weights and

defects are generated accordingly.

The reports are transmitted via the PHOENIXcMs interface to different users

and roles. Alarms are displayed in real-time and defective wheels are identified

together with their exact positions in the train and under the vehicle. The system

software differentiates between types of wheel defects like wheelflats, out of

roundness and polygonization.

Installation and maintenance of the PHOENixwoo/WJM sensors are unparalleled. The

small, light-weight and energy efficient design of the module allows for easy co­

location with other diagnostic functions in a cost effective way. Applying fibre optic

technology in the sensor design guarantees electromagnetic compatibility.

Applications

Condition Based Wheelset Maintenance Rail passenger transport is unparalleled in its ability to quickly and effectively transport large numbers of

passengers over relatively short distances. For operators the availability of their fleet is a key performance

indicator. PHOENixwiMtwoo functions measure on a continuous basis every wheel of the fleet and check for any

deviating force levels. Based on this information the Central Management Software (PHOENIXcMs) informs operators how the maintenance scheduling should be prioritized and adapted.

Alarming and Intervention Every wheelset passing over the PHOENixwiMtwoo sensors is analyzed and checked against pre-set tolerance levels. As soon as a wheelset that exceeds the pre-set limits is detected, an alarm message is generated. These

alarms are sent to the Central Management Software (PHOENIXcMs) within seconds of the train passing

together with additional information for the passage. PHOENIXcMs then sends a visual and/or acoustic alarm of these faulty wheelsets to the relevant operation and control center. This allows the signallers to respond to

the potential risk.
