Scanning of the characteristic dimensions of the control pattern for checking the railway wheel tread profile using a 3D scanner Atos core 200
Abstract
Wheels for rail vehicles are made according to precisely defined geometry and dimensions. The wear of the
wheel profile in operation is not uniform, so the initial profile changes. It is a consequence of the inevitable
slippage, which is influenced by a large number of factors. Certain changes in the profile can be important for
the safety of movement and riding quality, so the shape of the profile in operation must be regularly checked
through characteristic dimensions measurements: the flange thickness, the flange width and its slope.
Changing the characteristic measures can lead to: thinning of the flange over the allowed limit, which can lead
to its cracking, increase in the height of the flange, which can cause problems with derailment at crossings and
switches, reducing the slope of the flange, which can lead to derailment on the switch tongue. The paper
presents the verification of the dimensions and shape of the pattern for control wheel profile for the type of ...
tread shape S1002, which are used to control the wheel profile after reprofiling. The dimensions of the S1002
wheel profile are given in EN 13715 on the basis of which the control patterns are made. After making the
pattern or the control accessories, its dimensions were checked by scanning on a 3D scanner Atos core 200.
The resolution of the scanner is 0.08 mm, and its working surface is 200 x 150 mm. The 3D model was obtained
by scanning, from which the coordinates of the scanned profile were obtained with the help of the GOM Inspect
software package. Based on these coordinates, a comparison was made and a deviation from the nominal
profile.
