Requirements for wheel profile measurement

Wheels - one of the most important structural component of all rail vehicles - are subject to high mechanical stress and by this have considerable influence both on the running performance and riding comfort of the various kinds of vehicles. The wheel-rail-system is subject to a wide range of requirements and controls to ensure the required operational reliability.

Furthermore, the mechanical wear due to friction is a cost factor not to be disregarded.Therefore control measurements have to be taken in regular intervals, which are still carried out mostly by hand. Thus, subjective measuring and reading errors cannot be ruled out. Based on these criteria, the portable, laser-supported wheel-profile measuring system offers significant advantages for the acquisition of wheel profile parameters at a non-moving wheel.
