Diagnosing fretting in wrought wheels of a moving train. Transfer of the information to the nearest maintenance depot (MD).
Principle of operation of the system is based on noncontact laser inspection of geometrics of moving 3D objects using triangulation position sensors.
Noncontact measurement of parametric geometry features of moving railway vehicle wheelsets at speeds of up to 60 kph in a variety of climatic conditions.
Application of the system allows for enhancing operating reliability of railway units and minimizing risks of railroad emergency situations caused by wheelset defects.
Main measured parametric features of wheel pairs
- Wheel tread thickness
- Wheel flange thickness
- Sum and difference of flange thicknesses
Additional parametric features
- Wheel tread width
- Wheel tread diameter
- Distance between inner edges of wheel treads
- Angle of attack
