Method for determining wear value of rail vehicle, involves generating footprint profile of rail vehicle wheel by footprint material and determining wear value of rail vehicle in response to rail vehicle wheel footprint profile

摘要

The method involves generating a rail vehicle wheel footprint profile of rail vehicle wheel (3) by footprint material (6) positioned on a rail head (1) according to the application of force. The wear value of rail vehicle is determined in response to the rail vehicle wheel footprint profile. The rail vehicle wheel footprint profile is scanned by imaging sensor, ultrasound sensor and/or radar detector. An independent claim is included for device for determining wear value of rail vehicle.
